B.2. IPARAM: INTEGER PARAMETERS 455
• onoffkey.off Switch the option off.
• onoffkey.on Switch the option on.
Default value:
onoffkey.off
B.2.76
iparam.mio cont sol
Corresponding constant:
iparam.mio cont sol
Description:
Controls the meaning of the interior-point and basic solutions in mixed integer problems.
Possible values:
• miocontsoltype.itg The reported interior-point and basic solutions are a solution to the
problem with all integer variables fixed at the value they have in the integer solution. A
solution is only reported in case the problem has a primal feasible solution.
• miocontsoltype.itg rel In case the problem is primal feasible then the reported interiorpoint
and basic solutions are a solution to the problem with all integer variables fixed at
the value they have in the integer solution. If the problem is primal infeasible, then the
solution to the root node problem is reported.
• miocontsoltype.none No interior-point or basic solution are reported when the mixedinteger
optimizer is used.
• miocontsoltype.root The reported interior-point and basic solutions are a solution to the
root node problem when mixed-integer optimizer is used.
Default value:
miocontsoltype.none
B.2.77
iparam.mio cut level root
Corresponding constant:
iparam.mio cut level root
Description:
Controls the cut level employed by the mixed-integer optimizer at the root node. A negative
value means a default value determined by the mixed-integer optimizer is used. By adding the
appropriate values from the following table the employed cut types can be controlled.
