dc2 v1.1.2

• Fixed premature out-of-memory error when solving very large problem instances.

dc2 v1.1.1

Manuscript release.

dc2 v1.1.0

• Modified construction order so local searches are performed before path relinking.
• Minor optimizations.
• Added additional flags to choose different methods for local search and path relinking.
• Fixed incomplete path relinking error with Whitaker's methods.
• Changed default reduction strategies.

dc2 v1.0.0

Working version with:

• Local search strategies: Whitaker's first and best improvement and Resende & Werneck's method.
• Selection (a.k.a. reduction) strategies: random, random considering rank, SDBS, SDBS+, VR-heuristic.
• Dissimilitudes: Per-client-delta, mean geometric error and Hausdorff distance.
• Path relinking support.

From the previous release:

• Code was optimized.
• Whitaker's fast swap (both first and best improvement) was made compatible with path relinking, and can be used as a path relinking strategy.
• New parameters were added.
• Only p-median and SPLP problems are supported now.

First stable version

This version has support for a more general model that covers both p-median and SPLP.
However not all parameter combinations are supported (in particular path relinking and Whitaker's local search) and some command-line parameters were modified.
