问题 Is there a software package (preferable an application, not library) that creates Reduced Ordered Binary Decision Diagrams (ROBDDs) from a given truth table (in some text format)? 回答1: You can also try this: http://formal.cs.utah.edu:8080/pbl/BDD.php It is the best tool for BDDs I used so far. 回答2: With any BDD library you can do what you want. Of course, you must write a piece of code by yourself. If you are looking for a lightweight tool, I often use an applet like this to have a quick look

问题 I am working on optimization of a project. It contains a struct of an options in which user can select a single option at a time. In addition to the option, we also use a flag variable to check which option value is set for this record. In order to make it memory efficient I want to convert struct into a union. But How do I know that which variable value is set in union. Because there is no restriction in union to fetch a value of a variable even which is not set. struct options{ int basicPay

问题 Given a number N and a string, I need to split the string into exactly N pieces. For example, if N=3 abcd -> ["ab", "c", "d"] abcde -> ["ab", "cd", "e"] abcdef -> ["ab", "cd", "ef"] abcdefg -> ["abc", "de", "fg"] What would be the best way to achieve this (preferably in python)? My current (not working well enough) solution is chunkSize = int(ceil(len(myString) / float(numOfChunks))) chunks = [myString[i:i+chunkSize ] for i in range(0, len(myString), chunkSize )] 回答1: A generator that divides

问题 I decided to make a 2048 Command Line Edition but I'm having trouble getting the right tile movement... My current structure is that the board is a 2D array (4x4) of ints. When an input is received, it will try to push every tile in that direction (ignoring tiles with value 0), if it notices a change it will start over (Because a tile on the bottom row will have to go all the way up, not just one step up). However, a side effect of this is the following problem: [2][2][4] with the command ->

问题 I am running Manufacture Schedule (Using PHP Code), but currently its static (means I cannot add holidays OR I cannot change manufacture capacity - Current Manufacturing capacity is static 1700 SQFT per day) Please see below code $max = 1700; $dailyLeft = $max; $current = reset($priorityArraySum); $output = []; //$day = date('Y-m-d'); $day = date('Y-m-d'); while (true) { // echo $current."/".$dailyLeft."=".$day.PHP_EOL; if ( $current >= $dailyLeft ) { //$day=date('Y-m-d', strtotime($day.

问题 I am stuck, I need a small logic. I have two audio durations x = "00:00:07:18" y = "00:00:06:00" H : M: S: F Answer should be x + y = 00:00:13:18 H=hours S= seconds M=minutes F=frame My question is if x = "00:00:03:14" y = "00:00:13:18" answer should be x + y = **00:00:17:02** If the frame is greater than 30 it should increase 1 in second. I am using power shell. How can I determine the logic to calculate both of this? 回答1: Calculation of the first 3 parts ( hour:minute:second ), we can

问题 I have the following Source table where in there are records with start and end timestamps of a person logging in and logging out. employeeNumber | start_time | end_time john | 10/02/2020 16.30.000 | 11/02/2020 02.00.000 john | 10/02/2020 20.00.000 | 10/02/2020 22.00.000 john | 10/02/2020 23.00.000 | 11/02/2020 01.00.000 rick | 10/02/2020 10.00.000 | 10/02/2020 11.00.000 rick | 10/02/2020 13.00.000 | 10/02/2020 14.30.000 tom | 10/02/2020 09:00.000 | 10/02/2020 18.00.000 As you can see john

问题 i know that -> is a pointer |= is OR. what is the logical meaning of such line? TIMER0->ROUTELOC0 |= TIMER_ROUTELOC0_CC0LOC_LOC15 回答1: You're ORing in (setting) a value to a register. Your processor has a TIMER0 with a register ROUTELOC0. It likely has a bit that is "CC0LOC_LOC15" I recommend looking at the data sheet for your processor to figure out what that means specifically. 回答2: |= does not mean OR. | means OR. |= is similar to +=, that is A |= B is the equivalent of A = A | B So to

问题 I am havin a json with following structure which can go up to n level depth: [{ name: 'p1', child:[{ name: 'c1', child: [{ name: 'gc1', child: [] },{ name: 'gc2', child:[] }] },{ name: 'c2', child: [{ name: 'gc1', child: [] },{ name: 'gc2', child:[] }] },{ name: 'c3', child: [{ name: 'gc1', child: [] },{ name: 'gc2', child:[] }] }]},{ name: 'p2', child:[{ name: 'c1', child: [{ name: 'gc1', child: [] },{ name: 'gc2', child:[] }] },{ name: 'c2', child: [{ name: 'gc1', child: [] },{ name: 'gc2',
