v0.6.6-alpha

• Remove dependency on BranchAndBound class for the NodeInfoT::save method
• Make DantzigWolfe::Formulation annotations accessible
• Allow for submitting a decomposition by variable in DantzigWolfeDecomposition (to handle the case where only variables should be moved to SP)
• Fixes bug when removing constraints from a DantzigWolfe::Formulation

v0.6.5-alpha

• Fixes compiling error on some machines

v0.6.4-alpha

• Load columns from pool
• Make removal of infeasible columns optional (turned off by default for soft branching)

v0.6.3-alpha

• Implements branching with priorities
• Fixes printing errors for Solution::Primal
• Move all operators inside idol namespace

v0.6.2-alpha

• Fixes strong branching parameters being wrongly copied
• Only create multiplicity constraints when necessary

v0.6.1-alpha

• Fixes Column Generation with only one sub-problem

v0.6.0-alpha

• Complete refacto of Column Generation
• New stabilization by dual price smoothing implementation: Wentges, Neame
• Individual specifications for sub-problems
• Wrapper for minknap - though it is considered to be replaced by fontanf/knapsacksolver in the "near future"
• Stabilize HiGHS wrapper
• New node selection rule: BestEstimate
• Export branch-and-bound tree to csv to be used in conjunction with hlefebvr/idol-tree-dot
• Allows for copying optimizer factories, allow for elementary "optimizer arithmetic"
• Various bug fixes

v0.5.1-alpha

• Fixes support for robin_hood maps
• Reprot Fail status in branch-and-bound when nodes cannot be solved exactly

v0.5.0-alpha

• New node selection rule: best estimate

• Move all solver wrappers inside wrapper folder
• Fixed global installation
• Various bug fixes (in particular for Heuristics::IntegerMaster)
• improved unit test workflow

v0.4.0-alpha

• New default node type for branch-and-bound with variable branching allowing to trace back node history
