Superlinear Convergence of an Interior-Point Method Despite Dependent Constraints
We show that an interior-pointmethodfor monotonevariationalinequalitiesexhibits superlinear convergence provided that all the standard assumptions hold except for the well-known as...

Exact solutions to linear programming problems
The use of floating-point calculations limits the accuracy of solutions obtained by standard LP software. We present a simplex-based algorithm that returns exact rational solutio...

Simulating Magnetised Plasma with the Versatile Advection Code
Abstract. Matter in the universe mainly consists of plasma. The dynamics of plasmas is controlled by magnetic fields. To simulate the evolution of magnetised plasma, we solve the e...
