84 CHAPTER 9. PARAMETERS • MSK IPAR LICENSE SUPPRESS EXPIRE WRNS. Controls license manager client behavior. • MSK IPAR LICENSE WAIT. Controls if MOSEK should queue for a license if none is available. Logging parameters. • MSK IPAR LOG. Controls the amount of log information. • MSK IPAR LOG BI. Controls the amount of output printed by the basis identification procedure. A higher level implies that more information is logged. • MSK IPAR LOG BI FREQ. Controls the logging frequency. • MSK IPAR LOG CONCURRENT. Controls amount of output printed by the concurrent optimizer. • MSK IPAR LOG EXPAND. Controls the amount of logging when a data item such as the maximum number constrains is expanded. • MSK IPAR LOG FACTOR. If turned on, then the factor log lines are added to the log. • MSK IPAR LOG FEAS REPAIR. Controls the amount of output printed when performing feasibility repair. A value higher than one means extensive logging. • MSK IPAR LOG FILE. If turned on, then some log info is printed when a file is written or read. • MSK IPAR LOG HEAD. If turned on, then a header line is added to the log. • MSK IPAR LOG INFEAS ANA. Controls log level for the infeasibility analyzer. • MSK IPAR LOG INTPNT. Controls the amount of log information from the interior-point optimizers. • MSK IPAR LOG MIO. Controls the amount of log information from the mixed-integer optimizers. • MSK IPAR LOG MIO FREQ. The mixed-integer solver logging frequency. • MSK IPAR LOG NONCONVEX. Controls amount of output printed by the nonconvex optimizer. • MSK IPAR LOG OPTIMIZER. Controls the amount of general optimizer information that is logged. • MSK IPAR LOG ORDER. If turned on, then factor lines are added to the log. • MSK IPAR LOG PARAM. Controls the amount of information printed out about parameter changes. • MSK IPAR LOG PRESOLVE. Controls amount of output printed by the presolve procedure. A higher level implies that more information is logged. • MSK IPAR LOG RESPONSE. Controls amount of output printed when response codes are reported. A higher level implies that more information is logged. • MSK IPAR LOG SIM. Controls the amount of log information from the simplex optimizers. • MSK IPAR LOG SIM FREQ. Controls simplex logging frequency. • MSK IPAR LOG SIM NETWORK FREQ. Controls the network simplex logging frequency. • MSK IPAR LOG STORAGE. Controls the memory related log information. Mixed-integer optimization parameters.
85 • MSK IPAR LOG MIO. Controls the amount of log information from the mixed-integer optimizers. • MSK IPAR LOG MIO FREQ. The mixed-integer solver logging frequency. • MSK IPAR MIO BRANCH DIR. Controls whether the mixed-integer optimizer is branching up or down by default. • MSK IPAR MIO CONSTRUCT SOL. Controls if an initial mixed integer solution should be constructed from the values of the integer variables. • MSK IPAR MIO CONT SOL. Controls the meaning of interior-point and basic solutions in mixed integer problems. • MSK IPAR MIO CUT LEVEL ROOT. Controls the cut level employed by the mixed-integer optimizer at the root node. • MSK IPAR MIO CUT LEVEL TREE. Controls the cut level employed by the mixed-integer optimizer in the tree. • MSK DPAR MIO DISABLE TERM TIME. Certain termination criteria is disabled within the mixedinteger optimizer for period time specified by the parameter. • MSK IPAR MIO FEASPUMP LEVEL. Controls the feasibility pump heuristic which is used to construct a good initial feasible solution. • MSK IPAR MIO HEURISTIC LEVEL. Controls the heuristic employed by the mixed-integer optimizer to locate an initial integer feasible solution. • MSK DPAR MIO HEURISTIC TIME. Time limit for the mixed-integer heuristics. • MSK IPAR MIO HOTSTART. Controls whether the integer optimizer is hot-started. • MSK IPAR MIO KEEP BASIS. Controls whether the integer presolve keeps bases in memory. • MSK IPAR MIO MAX NUM BRANCHES. Maximum number of branches allowed during the branch and bound search. • MSK IPAR MIO MAX NUM RELAXS. Maximum number of relaxations in branch and bound search. • MSK IPAR MIO MAX NUM SOLUTIONS. Controls how many feasible solutions the mixed-integer optimizer investigates. • MSK DPAR MIO MAX TIME. Time limit for the mixed-integer optimizer. • MSK DPAR MIO MAX TIME APRX OPT. Time limit for the mixed-integer optimizer. • MSK DPAR MIO NEAR TOL ABS GAP. Relaxed absolute optimality tolerance employed by the mixed-integer optimizer. • MSK DPAR MIO NEAR TOL REL GAP. The mixed-integer optimizer is terminated when this tolerance is satisfied. • MSK IPAR MIO NODE OPTIMIZER. Controls which optimizer is employed at the non-root nodes in the mixed-integer optimizer. • MSK IPAR MIO NODE SELECTION. Controls the node selection strategy employed by the mixedinteger optimizer. • MSK IPAR MIO OPTIMIZER MODE. An exprimental feature. • MSK IPAR MIO PRESOLVE AGGREGATE. Controls whether problem aggregation is performed in the mixed-integer presolve.
