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
Alex Leontiev	f41b8b90ff	Blank module and first draft of solver API. At this point we have a skeleton of a new module (optim) which can barely compile properly (unlike previous commit). Besides, there is a first draft of solver and lpsolver (linear optimization solver) in this commit.	12 years ago

Alex Leontiev	47ce461d97	The initial commit for generic optimization Generic optimization package for openCV project, will be developed between the June and September of 2013. This work is funded by Google Summer of Code 2013 project. This project is about implementing several algorithms, that will find global maxima/minima of a given function on a given domain subject to a given constraints. All comments/suggestions are warmly appreciated and to be sent to alozz1991@gmail.com (please, mention the word "openCV" in topic of message, for I'm using the spam-filters)	12 years ago
