The parameter MSK IPAR LOG SENSITIVITY OPT controls the amount of debug information on internal calculations from the sensitivity analysis.
Chapter 9 Parameters Parameters grouped by functionality. Analysis parameters. Parameters controling the behaviour of the problem and solution analyzers. • MSK DPAR ANA SOL INFEAS TOL. If a constraint violates its bound with an amount larger than this value, the constraint name, index and violation will be printed by the solution analyzer. Basis identification parameters. • MSK IPAR BI CLEAN OPTIMIZER. Controls which simplex optimizer is used in the clean-up phase. • MSK IPAR BI IGNORE MAX ITER. Turns on basis identification in case the interior-point optimizer is terminated due to maximum number of iterations. • MSK IPAR BI IGNORE NUM ERROR. Turns on basis identification in case the interior-point optimizer is terminated due to a numerical problem. • MSK IPAR BI MAX ITERATIONS. Maximum number of iterations after basis identification. • MSK IPAR INTPNT BASIS. Controls whether basis identification is performed. • 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 DPAR SIM LU TOL REL PIV. Relative pivot tolerance employed when computing the LU factorization of the basis matrix. Behavior of the optimization task. Parameters defining the behavior of an optimization task when loading data. • MSK SPAR FEASREPAIR NAME PREFIX. Feasibility repair name prefix. 79
