The uniformity principle for traced monoidal categories has been introduced as a natural generalization of the uniformity principle (Plotkin's principle) for fixpoint operato...
We design an efficient algorithm that maximizes the sum of array elements of a subarray of a two-dimensional array. The solution can be used to find the most promising array porti...
This article discusses mutation testing strategies in the context of refinement. Here, a novel generalization of mutation testing techniques is presented to be applied to contract...
We investigate the reasons for which the existence of certain right adjoints implies the existence of some final coalgebras, and vice-versa. In particular we prove and discuss the...
In previous work [14] I introduced a generalised notion of coalgebra that is capable of modelling binary methods as they occur in object-oriented programming. An important problem...
