404 APPENDIX B. PARAMETERS<br />

B.1.4<br />

dparam.basis tol x<br />

Corresponding constant:<br />

dparam.basis tol x<br />

Description:<br />

Maximum absolute primal bound violation allowed in an optimal basic solution.<br />

Possible Values:<br />

Any number between 1.0e-9 and +inf.<br />

Default value:<br />

1.0e-6<br />

B.1.5<br />

dparam.check convexity rel tol<br />

Corresponding constant:<br />

dparam.check convexity rel tol<br />

Description:<br />

This parameter controls when the full convexity check declares a problem to be non-convex.<br />

Increasing this tolerance relaxes the criteria for declaring the problem non-convex.<br />

A problem is declared non-convex if negative (positive) pivot elements are detected in the cholesky<br />

factor of a matrix which is required to be PSD (NSD). This parameter controles how much this<br />

non-negativity requirement may be violated.<br />

If d i is the pivot element for column i, then the matrix Q is considered to not be PSD if:<br />

Possible Values:<br />

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

Default value:<br />

1e-10<br />

d i ≤ − |Q ii | ∗ check convexity rel tol<br />

B.1.6<br />

dparam.data tol aij<br />

Corresponding constant:<br />

dparam.data tol aij<br />

Description:<br />

Absolute zero tolerance for elements in A. If any value A ij is smaller than this parameter in<br />

absolute terms <strong>MOSEK</strong> will treat the values as zero and generate a warning.
