* QSimplex: new method solver, avoinding code replicationAnselmo Lacerda S. de Melo2009-07-221-0/+2
| | | | | | | | | | | The methods solveMin() and solveMax() had similar implementation, except by a "-1" multiplier. This commit includes a new private method called solver that is called by both solveMin() and solveMax(). A new enum 'solverFactor' was added admiting 2 values - Maximum (+1) and Minimum (-1).

* QSimplex: Adding the Simplex solver for linear systemsJesus Sanchez-Palencia2009-07-221-0/+120
This implementation is based on the iterative algorithm presented in http://en.wikibooks.org/wiki/Operations_Research/The_Simplex_Method. It is capable of giving us the solution to any n variable LP model. Although we focused on QGraphicsAnchorLayout, the solver is general enough for being reused in any other Qt classes if needed.
