Heinz Hofbauer	a26c4fa2a2	Bugfix for an overlapping size of image and template for matchTemplate. Example: img of size 10x10 and templ of size 11x9. In subsequent code this will results in either width or height of corrSize to be zero (0). Line 261 will call crossCorr which will then have a zero size of either blocksize.width or blocksize.height resulting in a division by zero crach in lines 137 or 138.	12 years ago

Alex Leontiev	a4a5e98cc0	Non-optimized simplex algorithm. This version is supposed to work on all problems (please, let me know if this is not so), but is not optimized yet in terms of numerical stability and performance. Bland's rule is implemented as well, so algorithm is supposed to allow no cycling. Additional check for multiple solutions is added (in case of multiple solutions algorithm returns an appropriate return code of 1 and returns arbitrary optimal solution). Finally, now we have 5 tests. Before Thursday we have 4 directions that can be tackled in parallel: ) Prepare the pull request! ) Make the code more clear and readable (refactoring) ) Wrap the core solveLP() procedure in OOP-style interface ) Test solveLP on non-trivial tests (possibly test against http://www.coin-or.org/Clp/)	12 years ago

Frédéric Devernay	b524e275c1	allow QtKit capture in secondary threads [NSRunLoop currentRunLoop] is not the same as in the main thread. see https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/F oundation/Classes/nsrunloop_Class/Reference/Reference.html "If no input sources or timers are attached to the run loop, this method exits immediately" The old code caused grabFrame() to return immediately if the capture was not done in the main thread. This code works correctly, even in secondary threads, provided that all capture functions are called in the same thread	12 years ago

Alex Leontiev	ddc0010e7d	The first draft of simplex algorithm, simple tests. What we have now corresponds to "formal simplex algorithm", described in Cormen's "Intro to Algorithms". It will work only if the initial problem has (0,0,0,...,0) as feasible solution (consequently, it will work unpredictably if problem was unfeasible or did not have zero-vector as feasible solution). Moreover, it might cycle. TODO (first priority) 1. Implement initialize_simplex() procedure, that shall check for feasibility and generate initial feasible solution. (in particular, code should pass all 4 tests implemented at the moment) 2. Implement Bland's rule to avoid cycling. 3. Make the code more clear. 4. Implement several non-trivial tests (??) and check algorithm against them. Debug if necessary. TODO (second priority) 1. Concentrate on stability and speed (make difficult tests)	12 years ago

Alex Leontiev	b216c0940c	Created skeleton for simplex method. Added LPSolver class together with two nested classes: LPFunction and LPConstraints. These represent function to be maximized and constraints imposed respectively. They are implementations of interfaces Function and Constraints respectively (latter ones are nested classes of Solver interface, which is generic interface for all optimization algorithms to be implemented within this project). The next step is to implement the simplex algorithm! First, we shall implement it for the case of constraints of the form Ax<=b and x>=0. Then, we shall extend the sets of problems that can be handled by the conversion to the one we've handled already. Finally, we shale concentrate on numerical stability and efficiency.	12 years ago
