LocalSolver 10.5

Release notes

  • LocalSolver cloud has been added
  • Two new operators COVER and FIND have been added.

LocalSolver cloud

LocalSolver cloud is a new way to optimize your models. With LocalSolver cloud, the optimization process is delegated to remote virtual machines entirely managed by the LocalSolver team.

Optimization on the cloud is performed seamlessly. LocalSolver APIs remain the same. Only the license file needs to be changed, allowing you to switch at any time between remote execution on the cloud or locally on your machines. All features of LocalSolver are supported except for external functions and black-box functions that cannot be transposed efficiently in the cloud.

For more details about the cloud mode and how it works technically, please check our documentation.

Contact our commercial team if you want to apply for a free trial. Please also note that any customer that already has a desktop, floating or a server commercial licence can get a free cloud license with up to 10000 hours of time credit on a standard cloud machine.
