## Gravity

Mathematical Modeling for Optimization and Machine Learning.

## Getting Started

The model below was implemented in Xcode:

## 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.

The figure below compares model build time between Gravity and JuMP on the PGLIB benchmarks.
