542 APPENDIX C. RESPONSE CODES rescode.wrn presolve outofspace The presolve is incomplete due to lack of space. rescode.wrn quad cones with root fixed at zero For at least one quadratic cone the root is fixed at (nearly) zero. This may cause problems such as a very large dual solution. Therefore, it is recommended to remove such cones before optimizing the problems, or to fix all the variables in the cone to 0. rescode.wrn rquad cones with root fixed at zero For at least one rotated quadratic cone at least one of the root variables are fixed at (nearly) zero. This may cause problems such as a very large dual solution. Therefore, it is recommended to remove such cones before optimizing the problems, or to fix all the variables in the cone to 0. rescode.wrn sol file ignored con One or more lines in the constraint section were ignored when reading a solution file. rescode.wrn sol file ignored var One or more lines in the variable section were ignored when reading a solution file. rescode.wrn sol filter Invalid solution filter is specified. rescode.wrn spar max len A value for a string parameter is longer than the buffer that is supposed to hold it. rescode.wrn too few basis vars An incomplete basis has been specified. Too few basis variables are specified. rescode.wrn too many basis vars A basis with too many variables has been specified. rescode.wrn too many threads concurrent The concurrent optimizer employs more threads than available. This will lead to poor performance. rescode.wrn undef sol file name Undefined name occurred in a solution. rescode.wrn using generic names Generic names are used because a name is not valid. For instance when writing an LP file the names must not contain blanks or start with a digit. rescode.wrn write changed names Some names were changed because they were invalid for the output file format.
543 rescode.wrn write discarded cfix The fixed objective term could not be converted to a variable and was discarded in the output file. rescode.wrn zero aij One or more zero elements are specified in A. rescode.wrn zeros in sparse col One or more (near) zero elements are specified in a sparse column of a matrix. It is redundant to specify zero elements. Hence, it may indicate an error. rescode.wrn zeros in sparse row One or more (near) zero elements are specified in a sparse row of a matrix. It is redundant to specify zero elements. Hence it may indicate an error.
