| Summary | 0000438: IMPLEMENTED: refactoring of the BLEIC optimizer | ||||||
| Description |
New version of the BLEIC optimizer has following improvements: * it uses new three-stage active set algorithm suggested by Elvira Illarionova, which combines gradient projection with iterations of equality constrained L-BFGS * because we do not have nested inner/outer iterations, more transparent stopping criteria can be specified for algorithm * it uses new constraint activation/deactivation strategy which can correctly handle degenerate constraints |
