We're excited to share that we are moving forward. We're leaving behind the LocalSolver brand and transitioning to our new identity: Hexaly. This represents a leap forward in our mission to enable every organization to make better decisions faster when faced with operational and strategic challenges.

This page is for an old version of Hexaly Optimizer. We recommend that you update your version and read the documentation for the latest stable release.

LocalSolver 6.5

Release notes

  • For models involving list variables, new moves have been introduced to better manage constraints based on count, indexOf or partition expressions. These moves are particularly effective on routing and scheduling problems.

  • For near-linear (discrete or continuous) problems, new moves have been introduced based on linear programming and mixed-integer linear programming techniques. These moves allow to intensify the search on near-linear models by exploring optimally larger neighborhoods.
