Hi everyone,
<div><br></div><div>I am using Clp to manually perform pivots. For a given vertex, I am checking every adjacent vertices based on the basis information.</div><div><br></div><div>To do that, my solver calls OsiClpSolverInterface::primalPivotResult( ... ). But the solver sometimes gives an error. The error occurs in ClpSimplexPrimal.cpp line 2927, which indicates CoinAssert (fabs(alpha_) > 1.0e-8).</div>
<div><br></div><div>I guess the error occurs when pivoting step size is too small. Is that right? If so, is there any way to properly handle this?</div><div><br></div><div>Thanks in advance,</div><div><br></div><div>Kibaek</div>
