An NLP Solver based on a primal-dual interior-point filter
ipfilter is a solver for nonlinear programming problems (defined by the minimization
of an objective function in a feasible region defined by equality and inequality
ipfilter is freely available for academic purposes (i.e., as a tool
for education or for basic research, as well as for benchmarking).
- ipfilter (version 0.3) is written in Fortran 90.
- ipfilter provides interfaces to AMPL and SIF and a user 'standard' Fortran interface.
- ipfilter is capable of solving large-scale NLPs. The sparse linear algebra uses MA57 from HSL.
- Version 0.3 requires first and second-order derivatives
for all the functions defining the problem.
- The file README.ipfilter
contains some information concerning the structure and usage of ipfilter.
- Version 0.3 of ipfilter can be obtained by sending e-mail to firstname.lastname@example.org.
