Summary

This package implements a discretize-and-relax approaches to computing state bounds and relaxations using the DynamicBounds.jl framework. These methods discretize the time domain over into a finite number of points and then compute valid relaxations at these time-points. Full documentation of this functionality may be found here in the DynamicBounds.jl website.

Installation

using Pkg; Pkg.add("DynamicBoundspODEsDiscrete")

or using the following command in the package manager environment

pkg > add DynamicBoundspODEsDiscrete

Note that this package can also be used directly via DynamicBounds.jl as the later package automatically reexports it.
