Last change on this file since 16373 was 16373, checked in by ddorfmei, 3 months ago

#2931:

  • upgraded Google OR-Tools to version 6.10
  • added TextValue and TextValueView to be able to display and edit a multiline string
  • added parameter to set solver specific parameters for supported solvers
  • added support for the Protocol Buffers representation of models (import/export)
  • added import of MPS models
  • added pause/stop functionality to CplexSolver and GlpkSolver
  • refactored wrapper (LinearSolver and related enums)
  • added new algorithm category Exact for LinearProgrammingAlgorithm
