contract_after_failure


The number of unsuccessful cycles prior to contraction.

Specification

Alias: none

Argument(s): INTEGER

Default: 4*number of variables

Description

In particular, coliny_solis_wets supports dynamic rescaling of the step length, and dynamic rescaling of the constraint penalty. The only new specification is contract_after_failure, which specifies the number of unsuccessful cycles which must occur with a specific delta prior to contraction of the delta.
