PEST and PEST++
PEST++ is a PEST-compatible suite of software whose functionality includes the following (the list is growing):
- highly parameterized inversion;
- global optimization through differential evolution;
- global sensitivity analysis;
- management optimization under chance constraints;
- posterior uncertainty analysis using a sophisticated iterative ensemble smoother.
Programs of the PEST++ suite are (almost) interchangeable, in terms of their input file requirements, with those of the PEST suite.
