See INSTALL.md for instructions on compiling Gravity

After running make, the Gravity executables can be found under Gravity/bin/


Getting Started

First, you will need to install an IDE, I recommend to choose among the following:

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.
