FortranFilterSLP

For a particular class of non-convex nonlinear programming problems, this FORTRAN implementation of FilterSLP uses sequential linear programming to find a (local) optimal solution.

original

This version dates from (at the latest) 4 July 2013.

  • It won't compile with modern f90 (specifically gcc version 9.4.0 - Ubuntu 9.4.0-1ubuntu1~20.04) due to some FORTRAN usage that's now illegal.

Specifically, two logical statements /= in lines 224 and 229 of rd_prob_da.f can no longer be compiled

master

This includes

  • Edits to allow it to be compiled with modern f90. Specifically the uses of /= have been replaced by .neqv.

As such, this represents the "best" version of the FORTRAN implementation of FilterSLP that @jajhall can come up with

Note

  • It calls EMSOL (see https://github.com/ERGO-Code/EMSOL)
  • To compile may require the-fno-range-check flag to cope with the mechanism used in EMSV.INC to set the 32nd bit in a 32-bit integer
  • No version of the FORTRAN implementation of FilterSLP is supported in any way
  • Anyone using a FORTRAN implementation of FilterSLP is strongly advised to continue using the version that they have!
