详细描述
Class CCplex to encapsulate access to the commercial cplex general purpose optimizer.
This class takes care of obtaining and releasing cplex licenses and sets up a number of optimization problems that are used in shogun, like for Multiple Kernel Learning, Linear Programming Machines and Linear Programming Boosting.
