This is what's leading to computing the LCM of all subsets -- all subsets effectively represent the sample space. You could end up with any possible set of components. The failure time for the device is based on the LCM of the set. The expected lifetime is therefore the average of the LCM of all sets.\r\n\r\nNote that this ought to include the LCM of sets with only one item (in which case we'd assume the LCM to be the element itself). The solution sketch seems to sabotage, perhaps because they handled it in a less elegant manner.\r\n\r\nWhat is meant by these states?\r\n-\r\nThe sketch author only uses the word *state* twice, but apparently manages to switch meanings. In the first use of the word *state* it appears they're talking about a possible selection of components. In the second use they're likely talking about possible failure times. They're could be muddling this terminology because their dynamic programming solution initializes values from one use of the word and the recurrence relation stems from the other.\r\n\r\n\r\nDoes dp stand for dynamic programming?\r\n-\r\nI would say either it does or it's a coincidence as the solution sketch seems to heavily imply dynamic programming.\r\n\r\nIf so, what recurrence relation is being solved? How is dp[i] computed from dp[i-1]?\r\n-\r\n\r\nAll I can think is that in their solution, *state* `i` represents a time to failure , `T(i)`, with the number of times this time to failure has been counted, `dp[i]`. The resulting sum would be to sum all `dp[i] * T(i)`.\r\n\r\n`dp[i][0]` would then be the failure times counted for only the first component. `dp[i][1]` would then be the failure times counted for the first and second component. `dp[i][2]` would be for the first, second, and third. Etc..\r\n\r\nInitialize `dp[i][0]` with zeroes except for `dp[T(c)][0]` (where `c` is the first component considered) which should be 1 (since this component's failure time has been counted once so far).\r\n\r\nTo populate `dp[i][n]` from `dp[i][n-1]` for each component `c`:\r\n\r\n- For each `i`, copy `dp[i][n-1]` into `dp[i][n]`.\r\n- Add 1 to `dp[T(c)][n]`.\r\n- For each `i`, add `dp[i][n-1]` to `dp[LCM(T(i), T(c))][n]`.\r\n\r\nWhat is this doing? Suppose you knew that you had a time to failure of `j`, but you added a component with a time to failure of `k`. Regardless of what components you had before, your new time to fail is `LCM(j, k)`. This follows from the fact that for two sets `A` and `B`, `LCM(A union B} = LCM(LCM(A), LCM(B))`.\r\n\r\nSimilarly, if we're considering a time to failure of `T(i)` and our new component's time to failure of `T(c)`, the resultant time to failure is `LCM(T(i), T(c))`. Note that we recorded this time to failure for `dp[i][n-1]` configurations, so we should record that many new times to failure once the new component is introduced.\r\n\r\nWhy do the big primes not contribute to the number of states?\r\n-\r\n> Each of them occurs either 0 or 1 times. Should the number of states not be multiplied by 2 for each of these primes (leading to a non-feasible state space again)?\r\n\r\nYou're right, of course. However, the solution sketch states that numbers with large primes are handled in another (unspecified) fashion.\r\n\r\nWhat would happen if we did include them?

This is what's leading to computing the LCM of all subsets -- all subsets effectively represent the sample space. You could end up with any possible set of components. The failure time for the device is based on the LCM of the set. The expected lifetime is therefore the average of the LCM of all sets.</p>\n\n<p>Note that this ought to include the LCM of sets with only one item (in which case we'd assume the LCM to be the element itself). The solution sketch seems to sabotage, perhaps because they handled it in a less elegant manner.</p>\n\n<h2>What is meant by these states?</h2>\n\n<p>The sketch author only uses the word <em>state</em> twice, but apparently manages to switch meanings. In the first use of the word <em>state</em> it appears they're talking about a possible selection of components. In the second use they're likely talking about possible failure times. They're could be muddling this terminology because their dynamic programming solution initializes values from one use of the word and the recurrence relation stems from the other.</p>\n\n<h2>Does dp stand for dynamic programming?</h2>\n\n<p>I would say either it does or it's a coincidence as the solution sketch seems to heavily imply dynamic programming.</p>\n\n<h2>If so, what recurrence relation is being solved? How is dp[i] computed from dp[i-1]?</h2>\n\n<p>All I can think is that in their solution, <em>state</em> <code>i</code> represents a time to failure , <code>T(i)</code>, with the number of times this time to failure has been counted, <code>dp[i]</code>. The resulting sum would be to sum all <code>dp[i] * T(i)</code>.</p>\n\n<p><code>dp[i][0]</code> would then be the failure times counted for only the first component. <code>dp[i][1]</code> would then be the failure times counted for the first and second component. <code>dp[i][2]</code> would be for the first, second, and third. Etc..</p>\n\n<p>Initialize <code>dp[i][0]</code> with zeroes except for <code>dp[T(c)][0]</code> (where <code>c</code> is the first component considered) which should be 1 (since this component's failure time has been counted once so far).</p>\n\n<p>To populate <code>dp[i][n]</code> from <code>dp[i][n-1]</code> for each component <code>c</code>:</p>\n\n<ul>\n<li>For each <code>i</code>, copy <code>dp[i][n-1]</code> into <code>dp[i][n]</code>.</li>\n<li>Add 1 to <code>dp[T(c)][n]</code>.</li>\n<li>For each <code>i</code>, add <code>dp[i][n-1]</code> to <code>dp[LCM(T(i), T(c))][n]</code>.</li>\n</ul>\n\n<p>What is this doing? Suppose you knew that you had a time to failure of <code>j</code>, but you added a component with a time to failure of <code>k</code>. Regardless of what components you had before, your new time to fail is <code>LCM(j, k)</code>. This follows from the fact that for two sets <code>A</code> and <code>B</code>, <code>LCM(A union B} = LCM(LCM(A), LCM(B))</code>.</p>\n\n<p>Similarly, if we're considering a time to failure of <code>T(i)</code> and our new component's time to failure of <code>T(c)</code>, the resultant time to failure is <code>LCM(T(i), T(c))</code>. Note that we recorded this time to failure for <code>dp[i][n-1]</code> configurations, so we should record that many new times to failure once the new component is introduced.</p>\n\n<h2>Why do the big primes not contribute to the number of states?</h2>\n\n<blockquote>\n <p>Each of them occurs either 0 or 1 times. Should the number of states not be multiplied by 2 for each of these primes (leading to a non-feasible state space again)?</p>\n</blockquote>\n\n<p>You're right, of course. However, the solution sketch states that numbers with large primes are handled in another (unspecified) fashion.</p>\n\n<p>What would happen if we did include them? The number of <em>states</em> we would need to represent would explode into an impractical number. Hence the author accounts for such numbers differently. Note that if a number less than or equal to 500 includes a prime larger than 19 the other factors multiply to 21 or less. This makes such numbers amenable for brute forcing, no tables necessary.</p>\n"}],"tags":["algorithm","computer-science","dynamic-programming","primes","prime-factoring"],"owner":{"reputation":146,"user_id":2472641,"user_type":"registered","profile_image":"https://www.gravatar.com/avatar/d734b762d636b11eca7cf2303325c2c0?s=128&d=identicon&r=PG","display_name":"MasterMind","link":"http://stackoverflow.com/users/2472641/mastermind"},"comments":[{"owner":{"reputation":313,"user_id":3455829,"user_type":"registered","profile_image":"http://i.stack.imgur.com/DxqTQ.gif?s=128&g=1","display_name":"Ralor","link":"http://stackoverflow.com/users/3455829/ralor"},"reply_to_user":{"reputation":2440,"user_id":2741705,"user_type":"registered","profile_image":"http://graph.facebook.com/1478197909/picture?type=large","display_name":"Pham Trung","link":"http://stackoverflow.com/users/2741705/pham-trung"},"edited":false,"score":1,"creation_date":1413904304,"post_id":26463250,"comment_id":41614065},{"owner":{"reputation":7580,"user_id":2095090,"user_type":"registered","accept_rate":100,"profile_image":"http://i.stack.imgur.com/4s3og.jpg?s=128&g=1","display_name":"Vincent van der Weele","link":"http://stackoverflow.com/users/2095090/vincent-van-der-weele"},"edited":false,"score":1,"creation_date":1413922983,"post_id":26463250,"comment_id":41624393},{"owner":{"reputation":146,"user_id":2472641,"user_type":"registered","profile_image":"https://www.gravatar.com/avatar/d734b762d636b11eca7cf2303325c2c0?s=128&d=identicon&r=PG","display_name":"MasterMind","link":"http://stackoverflow.com/users/2472641/mastermind"},"reply_to_user":{"reputation":7580,"user_id":2095090,"user_type":"registered","accept_rate":100,"profile_image":"http://i.stack.imgur.com/4s3og.jpg?s=128&g=1","display_name":"Vincent van der Weele","link":"http://stackoverflow.com/users/2095090/vincent-van-der-weele"},"edited":false,"score":0,"creation_date":1414017796,"post_id":26463250,"comment_id":41666332}],"comment_count":3,"is_answered":true,"view_count":186,"bounty_amount":100,"bounty_closes_date":1415297825,"answer_count":3,"score":9,"last_activity_date":1414773420,"creation_date":1413800137,"last_edit_date":1413922680,"question_id":26463250,"body_markdown":"**Given:** set <code>A = {a<sub>0</sub>, a<sub>1</sub>, ..., a<sub>N-1</sub>}</code> (<code>1 &leq; N &leq; 100</code>), with <code>2 &leq; a<sub>i</sub> &leq; 500</code>.\r\n\r\n**Asked:** Find the sum of all least common multiples (LCM) of all subsets of `A` of size at least 2.\r\n\r\nThe LCM of a set<code>B = {b<sub>0</sub>, b<sub>1</sub>, ..., b<sub>k-1</sub>}</code> is defined as the minimum integer <code>B<sub>min</sub></code> such that <code>b<sub>i</sub> | B<sub>min</sub></code>, for all <code>0 &leq; i < k</code>.\r\n\r\n**Example:**\r\n\r\nLet `N = 3` and `A = {2, 6, 7}`, then:\r\n\r\n LCM({2, 6}) = 6\r\n LCM({2, 7}) = 14\r\n LCM({6, 7}) = 42\r\n LCM({2, 6, 7}) = 42\r\n ----------------------- +\r\n answer 104\r\n\r\nThe naive approach would be to simply calculate the LCM for all <code>O(2<sup>N</sup>)</code> subsets, which is not feasible for reasonably large `N`.\r\n\r\n---\r\n\r\n**Solution sketch:**\r\n\r\nThe problem is obtained from a competition<sup>*</sup>, which also provided a [solution sketch][1].

I ended up with about 5 different regexp strings, which is not as clean as Dired+ presently offers.</p>\n\n \n\n<pre><code>(defvar folder-listing-before-filename-regexp\n (concat\n \"\\\\(^ +d[slrwxt+-]+\\\\)\" ;; 1 permissions\n \"\\\\(\\s\\\\)\" ;; 2\n \"\\\\([0-9]+\\\\|\\s+[0-9]+\\\\)\" ;; 3 some small numbers\n \"\\\\(\\s\\\\)\" ;; 4\n \"\\\\([a-zA-Z]+\\\\)\" ;; 5 user\n \"\\\\(\\s\\\\)\" ;; 6\n \"\\\\([a-zA-Z]+\\\\)\" ;; 7 group\n \"\\\\(\\s\\\\)\" ;; 8\n \"\\\\([\\s0-9.kKMGT]+\\\\)\" ;; 9 size\n \"\\\\(\\s\\\\)\" ;; 10\n \"\\\\([0-9-]+\\\\)\" ;; 11 date\n \"\\\\(\\s\\\\)\" ;; 12\n \"\\\\([0-9:]+\\\\)\" ;; 13 time\n \"\\\\(\\s\\\\)\")) ;; 14\n\n(defvar file-listing-before-filename-regexp\n (concat\n \"\\\\(^ +[^d][slrwxt+-]+\\\\)\" ;; 1 permissions\n \"\\\\(\\s\\\\)\" ;; 2\n \"\\\\([0-9]+\\\\|\\s+[0-9]+\\\\)\" ;; 3 some small numbers\n \"\\\\(\\s\\\\)\" ;; 4\n \"\\\\([a-zA-Z]+\\\\)\" ;; 5 user\n \"\\\\(\\s\\\\)\" ;; 6\n \"\\\\([a-zA-Z]+\\\\)\" ;; 7 group\n \"\\\\(\\s\\\\)\" ;; 8\n \"\\\\([\\s0-9.kKMGT]+\\\\)\" ;; 9 size\n \"\\\\(\\s\\\\)\" ;; 10\n \"\\\\([0-9-]+\\\\)\" ;; 11 date\n \"\\\\(\\s\\\\)\" ;; 12\n \"\\\\([0-9:]+\\\\)\" ;; 13 time\n \"\\\\(\\s\\\\)\")) ;; 14\n\n(defvar diredp-font-lock-keywords-1\n (list\n '(\"[^ .]\\\\.\\\\(git\\\\)$\" 1 'diredp-git-face t)\n '(\"[^ .]\\\\.\\\\(app\\\\)$\" 1 'diredp-app-face t)\n\n (list folder-listing-before-filename-regexp\n (list \"\\\\(.+\\\\)$\" nil nil (list 0 diredp-dir-priv 'keep t))) ; folder-name\n\n (list file-listing-before-filename-regexp\n (list \"\\\\(.+\\\\)$\" nil nil (list 0 diredp-file-name 'keep t))) ; file-name\n ))\n</code></pre>\n"}],"tags":["dired","regular-expressions"],"owner":{"reputation":144,"user_id":2287,"user_type":"registered","profile_image":"https://www.gravatar.com/avatar/5f4ed4b573c4e38444c6fc54b28076c0?s=128&d=identicon&r=PG","display_name":"lawlist","link":"http://emacs.stackexchange.com/users/2287/lawlist"},"comments":[{"owner":{"reputation":1217,"user_id":45,"user_type":"registered","accept_rate":93,"profile_image":"https://www.gravatar.com/avatar/073274c272b84eed27790fc3e5231d46?s=128&d=identicon&r=PG&f=1","display_name":"King Shimkus","link":"http://emacs.stackexchange.com/users/45/king-shimkus"},"edited":false,"score":0,"post_type":"question","creation_date":1414715005,"post_id":2881,"comment_id":3933,"body_markdown":"Have you tried looking into other options?

(You can skip down to the second code-block below, if you want.)\r\n\r\nI love the concept of `imenu` (esp. when integrated with `helm`) and I think it has great potential to improve my workflow...assuming I learn how to correctly set definitions for `imenu` categories. \r\n\r\nAs a simplified example, let's say that I'd like to add a few definitions to my `init` file's `imenu` which would be useful when making updates - namely, the list of imported packages.\r\n\r\nLet's consider the following three lines as the code we want to parse (purely illustrative; my `init` file doesn't actually have an explicit line for importing `dired` and `electric`):\r\n\r\n (defconst dc/default-directory "/path/to/directory")\r\n (use-package dired)\r\n (use-package electric)\r\n\r\nIn order to extract the constants and package names in `imenu`, I've included the code below in my `init.el` file.
