This Julia package allows us to specify a set of constraints on real-valued variables, given by inequalities, and rigorously calculate (inner and outer approximations to) the feasible set, i.e. the set that satisfies the constraints.
The package is based on interval arithmetic using the
IntervalArithmetic.jl package (co-written by the author),
in particular multi-dimensional IntervalBoxes (i.e. Cartesian products of one-dimensional intervals).
Documentation for the package is available here.
The best way to learn how to use the package is to look at the tutorial, available in the organisation webpage here.
