Hi,

I was wondering if there is any way to return the solution for each iteration using Dual Simplex for now (2022) via callback function?

Thanks!

  Hi,

  No, unfortunately there is no way to access intermediate simplex solutions during a callback. In the SIMPLEX callback you can only retrieve current objective value, iteration, and infeasibilities.

  As a workaround, you could set parameter IterationLimit=1, and iteratively call optimize() (that ends after a single simplex iteration) and retrieve the according solution.

  Best regards,
  Mario
