541 rescode.wrn mio infeasible final The final mixed-integer problem with all the integer variables fixed at their optimal values is infeasible. rescode.wrn mps split bou vector A BOUNDS vector is split into several nonadjacent parts in an MPS file. rescode.wrn mps split ran vector A RANGE vector is split into several nonadjacent parts in an MPS file. rescode.wrn mps split rhs vector An RHS vector is split into several nonadjacent parts in an MPS file. rescode.wrn name max len A name is longer than the buffer that is supposed to hold it. rescode.wrn no dualizer No automatic dualizer is available for the specified problem. The primal problem is solved. rescode.wrn no global optimizer No global optimizer is available. rescode.wrn no nonlinear function write The problem contains a general nonlinear function in either the objective or the constraints. Such a nonlinear function cannot be written to a disk file. Note that quadratic terms when inputted explicitly can be written to disk. rescode.wrn nz in upr tri Non-zero elements specified in the upper triangle of a matrix were ignored. rescode.wrn open param file The parameter file could not be opened. rescode.wrn param ignored cmio A parameter was ignored by the conic mixed integer optimizer. rescode.wrn param name dou The parameter name is not recognized as a double parameter. rescode.wrn param name int The parameter name is not recognized as a integer parameter. rescode.wrn param name str The parameter name is not recognized as a string parameter. rescode.wrn param str value The string is not recognized as a symbolic value for the parameter.

540 APPENDIX C. RESPONSE CODES<br />

rescode.wrn empty name<br />

A variable or constraint name is empty. <strong>The</strong> output file may be invalid.<br />

rescode.wrn ignore integer<br />

Ignored integer constraints.<br />

rescode.wrn incomplete linear dependency check<br />

<strong>The</strong> linear dependency check(s) is not completed. Normally this is not an important warning<br />

unless the optimization problem has been formulated with linear dependencies which is bad<br />

practice.<br />

rescode.wrn large aij<br />

A numerically large value is specified for an a i,j element in A. <strong>The</strong> parameter dparam.data tol aij large<br />

controls when an a i,j is considered large.<br />

rescode.wrn large bound<br />

A numerically large bound value is specified.<br />

rescode.wrn large cj<br />

A numerically large value is specified for one c j .<br />

rescode.wrn large con fx<br />

An equality constraint is fixed to a numerically large value. This can cause numerical problems.<br />

rescode.wrn large lo bound<br />

A numerically large lower bound value is specified.<br />

rescode.wrn large up bound<br />

A numerically large upper bound value is specified.<br />

rescode.wrn license expire<br />

<strong>The</strong> license expires.<br />

rescode.wrn license feature expire<br />

<strong>The</strong> license expires.<br />

rescode.wrn license server<br />

<strong>The</strong> license server is not responding.<br />

rescode.wrn lp drop variable<br />

Ignored a variable because the variable was not previously defined. Usually this implies that a<br />

variable appears in the bound section but not in the objective or the constraints.<br />

rescode.wrn lp old quad format<br />

Missing ’/2’ after quadratic expressions in bound or objective.
