CPXXparamsetadddbl and CPXparamsetadddbl

The routine CPXXparamsetadddbl/CPXparamsetadddbl adds a parameter of type double to a parameter set.

int CPXXparamsetadddbl( CPXCENVptr env, CPXPARAMSETptr ps, int whichparam, double dvalue)

int CPXparamsetadddbl( CPXCENVptr env, CPXPARAMSETptr ps, int whichparam, double dvalue)

Description

The routine CPXXparamsetadddbl/CPXparamsetadddbl adds a parameter of type double parameter to a parameter set. If the parameter does not yet exist in the parameter set then it gets added with the specified value. If the parameter is already in the parameter set then its current value will be replaced by the specified value.

The CPLEX Parameters Reference Manual provides a list of parameters with their types, options, and default values.

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
ps: A pointer to the CPLEX parameter set as returned by CPXXparamsetcreate/CPXparamsetcreate.
whichparam: The symbolic constant (or reference number) of the parameter to add.
newvalue: The new value of the parameter.

Return

The routine returns 0 (zero) if successful and nonzero if an error occurs.

Example


        status = CPXparamsetadddbl (env, ps, CPXPARAM_TimeLimit, 1000.0);
