What is "worhp"

WORHP, pronounced like the English word "warp", also referred to as eNLP (European NLP solver) by ESA, is a mathematical software library for solving continuous large scale nonlinear optimization problems numerically. The acronym WORHP is sometimes spelled out as "We Optimize Really Huge Problems", its primary intended application. WORHP is a hybrid Fortran and C implementation and can be used from C/ C++ and Fortran programs using different interfaces of varying complexity and flexibility. In addition interfaces for the modelling environments MATLAB, CasADi and AMPL exist.
