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.
