Gravity

Mathematical Modeling for Optimization and Machine Learning.

Getting Started

The model below was implemented in Xcode:

Kapture_Stable_Set

Some Numerical Results:

Performance Profile on ACOPF

The first figure below is a performance profile illustrating percentage of instances solved as a function of time.
The figure compares Gravity, JuMP and AMPL's NL interface (used by AMPL and Pyomo) on all standard instances found in the PGLIB benchmark library.
