[FlagsAttribute] public enum HeuristicSearchSelect
| Member name | Value | Description |
|---|---|---|
| RINS | 1 | LNS heuristic with a large neighborhood. Potentially expensive but good for finding solutions that differs significantly from the incumbent. Use HEURSEARCHRINSSTRATEGY instead. |
| LPFirst | 2 | LNS heuristic with a small neighborhood centered around a node LP solution. Use HEURSEARCHLPFIRSTSTRATEGY instead. |
| MIPFirst | 4 | LNS heuristic with a small neighborhood centered around an integer solution. This heuristic will often provide smaller, incremental improvements to an incumbent solution. Use HEURSEARCHMIPFIRSTSTRATEGY instead. |
| CombineSols | 8 | LNS heuristic with a neighborhood set up through the combination of multiple integer solutions. Use HEURSEARCHCOMBINESTRATEGY instead. |
| ZeroObj | 32 | LNS heuristic without an objective function. Called seldom and only when no feasible solution is available. Use HEURSEARCHZEROOBJSTRATEGY instead. |
| Analytic | 64 | LNS heuristic with an auxiliary objective function. Called seldom and only when no feasible solution is available. Use HEURSEARCHANALYTICSTRATEGY instead. |
