Here's the link to the Web Player version,Http://www-scf.usc.edu/~taian/pages/sph/builds/12212014/12212014.htmlWeekend Project. Just wanted to rejuvenate my graphics programming stuff.It was originally written-C, not even C + +. Most operations is done with entire memcpy, memset.In C#/unity.. Damn. So slow, guess would has to relearn GPGPU.To re-write the SPH Solver 4 years ago in unity.The original C OpenGL program in c#/unity slow a lot, of course,

WPS Table implements the method of Solver calculation: Create a new WPS form file and enter relevant information about product A and b according to the conditions of the problem. Set a variable cell (equivalent to a free variable), there are two free variables in the argument, so set two variable cells (in order to be obvious, marked with red, can not be marked in normal operation) Set Target function Set the fi

Compile z3 solver on redhat6.4, redhat6.4z3 Because of the project requirements, we used Microsoft's z3 Solver For constraints, but the z3 solver did not release the compiled binary version on the Red Hat platform, our operating environment is RedHat Enterprise 6.4, so we need to compile the corresponding binary. Z3 is an excellent SMT

Seek Sudoku, only ask to make an answer.Just beginning to understand test instructions wrong, think the answer is unique, so did not do it for a long time, found that the answer is not unique after using backtracking. (or a reference to others)public class Solution {public void Solvesudoku (char[][] board) {hashset[] HashSet = new Hashset[27];for (int i = 0; I Backtracking is still relatively simple, that is, in the implementation of the time, if you want to improve the speed and space for the o

Problem DescriptionAs is known to all, sepr (Liangjing Wang) had solved more than 1400 problems on POJ, but nobody know the days and nights he had spent on solving problems.Xiangsanzi (Chen Zhou) was a perfect problem solver too. Now this is a story about them happened two years ago.On March 2006, sepr Xiangsanzi were new comers of hustacm team and both of them want to be "The Best New Comers of March", so they spent days and nighthts solving problem

have been processed several times there is a certain pixel difference, or there may be a watermark.After solving the target position of the slider, are we just going to follow the displacement to drag the slider? The answer is no, look:You can see that there is a distance between the slider and the background image before sliding, it is necessary to make a displacement adjustment, after observation, this value is about 7 pixels, so: the final sliding displacement = the number of left pixels of
