The package contains four OLIM methods for computing the quasi-potential in 2D on a regular rectangular mesh:
OLIM_midpoint.c - based on the midpoint quadrature rule;
OLIM_trapezoid.c - basedon the trapezoid quadrature rule;
OLIM_simpson.c - based on Simpson's quadrature rule;
OLIM_righthand.c - based on the righthand rectangle quadrature rule;
as well as two txt input files and README.pdf
A technical description/user guide for the package is given in README.pdf
The methods are described in detail in
