releaseLicence ( ) ¶ Release a previously obtained CPLEX licence setMemoryEmphasis ( yesOrNo=False ) ¶ Make cplex try to conserve memory at the expense of The licence is kept until releaseLicence() is called. Outputs the variables in var as a sparse matrix,Ĭopyright (c) Stuart Mitchell 2007 grabLicence ( ) ¶ Returns True if a CPLEX licence can be obtained. Solution time actualResolve ( lp ) ¶ looks at which variables have been modified and changes them actualSolve ( lp ) ¶ Solve a well formulated lp problem available ( ) ¶ True if the solver is available callSolver ( isMIP ) ¶ Solves the problem with cplex changeEpgap ( epgap=0.0001 ) ¶ Change cplex solver integer bound gap tolerence findSolutionValues ( lp, numcols, numrows ) ¶ getSparseCols ( vars, lp, offset=0, defBound=1e+20 ) ¶ Initializes the CPLEX_DLL mip: if False the solver will solve a MIP as an msg: displays information from the solver to epgap: sets the integer bound logfilename: sets the filename of the cplex emphasizeMemory: makes the solver emphasize Memory over The ctypes library interface to the cplex api in CPLEX_DLL.lib This solver wraps the c library api of cplex.įor api functions that have not been wrapped in this solver please use
