Getting Started
First, you will need to install an IDE, I recommend to choose among the following:
Visual Studio | Clion | Xcode | Eclipse
:-------------------------:|:-------------------------:|:-------------------------:|:-------------------------:
| 
| 
| 
Then, follow the instructions presented in INSTALL.md.
After building, the Gravity library can be found under Gravity/lib, and the executables (from Gravity/examples) can be found under Gravity/bin/Release
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.
Performance Profile on Inverse Ising Model
