Improved Total Variation-Type Regularization Using Higher Order Edge Detectors
We present a novel deconvolution approach to accurately restore piecewise smooth signals from blurred data. The first stage uses Higher Order Total Variation restorations to obtai...

Higher Order Pheromone Models in Ant Colony Optimisation
Ant colony optimisation is a constructive metaheuristic that successively builds solutions from problem-specific components. A parameterised model known as pheromone--an analogue o...

Structure of a Proof-Producing Compiler for a Subset of Higher Order Logic
We give an overview of a proof-producing compiler which translates recursion equations, defined in higher order logic, to assembly language. The compiler is implemented and valida...

The Complexity of Games on Higher Order Pushdown Automata
Abstract. We prove an n-exptime lower bound for the problem of deciding the winner in a reachability game on Higher Order Pushdown Automata (HPDA) of level n. This bound matches th...
