B.1. DPARAM: DOUBLE PARAMETERS 425<br />

B.1.63<br />

dparam.presolve tol x<br />

Corresponding constant:<br />

dparam.presolve tol x<br />

Description:<br />

Absolute zero tolerance employed for x j in the presolve.<br />

Possible Values:<br />

Any number between 0.0 and +inf.<br />

Default value:<br />

1.0e-8<br />

B.1.64<br />

dparam.qcqo reformulate rel drop tol<br />

Corresponding constant:<br />

dparam.qcqo reformulate rel drop tol<br />

Description:<br />

This parameter determines when columns are dropped in incomplete cholesky factorization doing<br />

reformulation of quadratic problems.<br />

Possible Values:<br />

Any number between 0 and +inf.<br />

Default value:<br />

1e-15<br />

B.1.65<br />

dparam.sim lu tol rel piv<br />

Corresponding constant:<br />

dparam.sim lu tol rel piv<br />

Description:<br />

Relative pivot tolerance employed when computing the LU factorization of the basis in the<br />

simplex <strong>optimizer</strong>s and in the basis identification procedure.<br />

A value closer to 1.0 generally improves numerical stability but typically also implies an increase<br />

in the computational work.<br />

Possible Values:<br />

Any number between 1.0e-6 and 0.999999.<br />

Default value:<br />

0.01
