![]() ![]() One or more lines in the constraint section were ignored when reading a solution file. The final mixed-integer problem with all the integer variables fixed at their optimal values is infeasible. "MSK_RES_WRN_MIO_INFEASIBLE_FINAL" (270) ¶ "MSK_RES_WRN_NO_GLOBAL_OPTIMIZER" (251) ¶ One or more non-zero elements were dropped in the Q matrix in the objective. Non-zero elements specified in the upper triangle of a matrix were ignored. Usually this implies that a variable appears in the bound section but not in the objective or the constraints. Ignored a variable because the variable was not previously defined. Missing ‘/2’ after quadratic expressions in bound or objective. "MSK_RES_WRN_MPS_SPLIT_BOU_VECTOR" (72) ¶Ī BOUNDS vector is split into several nonadjacent parts in an MPS file. ![]() "MSK_RES_WRN_MPS_SPLIT_RAN_VECTOR" (71) ¶Ī RANGE vector is split into several nonadjacent parts in an MPS file. "MSK_RES_WRN_MPS_SPLIT_RHS_VECTOR" (70) ¶Īn RHS vector is split into several nonadjacent parts in an MPS file. "MSK_RES_WRN_SPAR_MAX_LEN" (66) ¶Ī value for a string parameter is longer than the buffer that is supposed to hold it. "MSK_RES_WRN_NAME_MAX_LEN" (65) ¶Ī name is longer than the buffer that is supposed to hold it. One or more zero elements are specified in A. "MSK_RES_WRN_LARGE_CJ" (57) ¶Ī numerically large value is specified for one \(c_\) is considered large. "MSK_RES_WRN_LARGE_CON_FX" (54) ¶Īn equality constraint is fixed to a numerically large value. "MSK_RES_WRN_LARGE_UP_BOUND" (53) ¶Ī numerically large upper bound value is specified. "MSK_RES_WRN_LARGE_LO_BOUND" (52) ¶Ī numerically large lower bound value is specified. "MSK_RES_WRN_LARGE_BOUND" (51) ¶Ī numerically large bound value is specified. The optimizer terminated for internal reasons. The optimizer terminated due to some internal reason. The optimizer terminated due to numerical problems. This indicates serious numerical problems and a possibly badly formulated problem. The optimizer terminated as the maximum number of set-backs was reached. The optimizer terminated due to the return of Near feasible or near infeasible problems. Some common causes of stalling are a) badly scaled models, b) The returned basic solution likely to have high accuracy, even though The interior-point optimizer with basis identification turned on, Please note that if a linear optimization problem is solved using Most likely good enough for most practical purposes. ![]() If the solution status is optimal the solution is Therefore, it is recommended to check the Stalling happens near the optimum, and the returned solution mayīe of good quality. In many cases this happens if the problem is badly scaled or Making reasonable progress and that it makes no sense to continue. Stalling means that numerical problems prevent the optimizer from The optimizer is terminated due to slow progress. The mixed-integer optimizer terminated as the maximum number of feasible solutions was reached. The mixed-integer optimizer terminated as the maximum number of branches was reached. The mixed-integer optimizer terminated as the maximum number of relaxations was reached. The optimizer terminated with an objective value outside the objective range. The optimizer terminated at the maximum amount of time. The optimizer terminated at the maximum number of iterations. The enumeration type containing all response codes. The numerical code (in brackets) identifies the response in error messages and in the log output. ![]()
