Writing files

These routines write problem information to formatted a file.

CPXXdperwrite and CPXdperwrite
When solving degenerate linear programs with the dual simplex method, CPLEX may initiate a perturbation of the objective function of the problem in order to improve performance.
CPXXdualwrite and CPXdualwrite
The routine CPXXdualwrite/CPXdualwrite writes a dual formulation of the current CPLEX problem object.
CPXXembwrite and CPXembwrite
The routine CPXXembwrite/CPXembwrite writes out the network embedded in the selected problem object.
CPXXwriteparam and CPXwriteparam
The routine CPXXwriteparam/CPXwriteparam writes the name and current setting of CPLEX parameters that are not at their default setting in the environment specified by env.
CPXXwriteprob and CPXwriteprob
The routine CPXXwriteprob/CPXwriteprob writes a CPLEX problem object to a file in one of the formats in the table.
CPXXmbasewrite and CPXmbasewrite
The routine CPXXmbasewrite/CPXmbasewrite writes the most current basis associated with a CPLEX problem object to a file.
CPXXpperwrite and CPXpperwrite
When solving degenerate linear programs with the primal simplex method, CPLEX may initiate a perturbation of the bounds of the problem in order to improve performance.
CPXXsolwrite and CPXsolwrite
The routine CPXXsolwrite/CPXsolwrite writes a solution file for the selected CPLEX problem object.
CPXXsolwritesolnpoolall and CPXsolwritesolnpoolall
The routine CPXXsolwritesolnpoolall/CPXsolwritesolnpoolall writes all the solutions in the solution pool to a file for the selected CPLEX problem object.
CPXXsolwritesolnpool and CPXsolwritesolnpool
The routine CPXXsolwritesolnpool/CPXsolwritesolnpool writes a solution file, using either the incumbent solution or a solution from the solution pool, for the selected CPLEX problem object.
