# XSLP_DELTA_X, SLPDELTA_X

Description | Minimum absolute value of delta coefficients to be retained
Type | Double
Topic area | Derivatives
Default value | 1.0e-6
Notes | If the value of a coefficient in a delta column is less than this value, it will be reset to zero. Larger values of XSLP_DELTA_X will result in matrices with fewer elements, which may be easier to solve. However, there will be increased likelihood of local optima as some of the small relationships between variables and constraints are deleted. There may also be increased difficulties with singular bases resulting from deletion of pivot elements from the matrix.
