OPTANO.Modeling 3.4.0.489

The OPTANO Modeling library allows you to use C# as a Modeling language for mathematical optimization (mixed integer programming (MIP) and linear programming (LP)). It has a lightweight footprint and connects to several solvers.

There is a newer prerelease version of this package available.
See the version list below for details.

Version 3.4 (2020-07-16)

  • Feature: Add support for CPLEX 12.10
  • Feature: The internal LP writer (used as fallback for solvers that do not provide a native option for exporting a model) now orders variables and constraints by name.
  • Feature: Updated the limited license for all versions of Gurobi 8.*.
  • Fix: The automatic substitution for OR-Constraint was not properly working for all cases. This also affected the substitution of Implies-Constraints.
  • Fix: When Products with "very small" (i.e. &lt; 1e-6) factors were normalized, the complete product was declared to be 0.
    Internally, it was assumed that numbers &lt; ModelScope.EPSILON are "equal" to 0, without checking if the "final" result might be larger than 1e-6.
    • E.g.: p = 1/10000000 * (1000 * x)
      Previously: p = 0
      Now: p = 1/10000 * x
