Its historical changelog records Gecode 1.0.0 on 2005-12-06. ### Adoption history Gecode's official news archive tracks its use in solver and modeling ecosystems: FlatZinc support was announced in 2007, repeated MiniZinc Challenge wins were reported from 2008 through 2012, Homebrew availability was announced in 2011, and SAP adoption for advanced variant configuration was reported in 2018. ### How it is used Developers use Gecode as a C++ toolkit and through command-line front ends such as FlatZinc and MiniZinc-related tooling. The official documentation emphasizes tutorial and reference material for modeling, search, installation, linking, and platform-specific builds. ### Why package nerds care Gecode is significant in package collections because it is both a library and a solver executable dependency for constraint-programming workflows, especially MiniZinc and FlatZinc users who care about solver availability, ABI compatibility, and platform packaging. ### Timeline - 2005: Gecode 1.0.0 released. - 2007: FlatZinc for Gecode 1.0 released. - 2008-2012: Gecode won MiniZinc Challenge gold medals across multiple years. - 2011: Gecode became installable on Mac OS via Homebrew. - 2018: SAP use of Gecode for advanced variant configuration was reported. - 2019: Gecode 6.2.0 released. ### Related projects - MiniZinc, FlatZinc, AMPL, ECLiPSe, YAP Prolog, and SAP advanced variant configuration are named in Gecode's official site or news archive as related interfaces, uses, or integrations. ### Sources -
