Missing types in MPSolver.OptimizationProblemType #54

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
In rev3750 (Java binaries,  OS X),   class 
com.google.ortools.linearsolver.MPSolver constructor takes two arguments. The 
second argument is used to specify MPSolver.OptimizationProblemType as one of 
the following three enum types:  
    CBC_MIXED_INTEGER_PROGRAMMING
    CLP_LINEAR_PROGRAMMING
    GLOP_LINEAR_PROGRAMMING.

The other types are missing, and the corresponding solvers cannot be 
instantiated.  Following are examples of missing types:
     GLPK_LINEAR_PROGRAMMING
     SULUM_LINEAR_PROGRAMMING
    GUROBI_LINEAR_PROGRAMMING
    CPLEX_LINEAR_PROGRAMMING
    SCIP_MIXED_INTEGER_PROGRAMMING
    GLPK_MIXED_INTEGER_PROGRAMMING
    SULUM_MIXED_INTEGER_PROGRAMMING
    GUROBI_MIXED_INTEGER_PROGRAMMING
    CPLEX_MIXED_INTEGER_PROGRAMMING

Hello, 

Unfortunately, for licensing issues, we cannot distribute binaries with these 
solvers embedded.
You need to recompile from sources, after adding the directory path in 
Makefile.local.
