A robust implementation of a sequential quadratic programming algorithm with successive error restoration
We consider sequential quadratic programming (SQP) methods for solving constrained nonlinear programming problems. It is generally believed that SQP methods are sensitive to the a...

Propositional Dynamic Logic for Message-Passing Systems
We examine a bidirectional Propositional Dynamic Logic (PDL) for message sequence charts (MSCs) extending LTL and TLC− . Every formula is translated into an equivalent communicat...

Bounded-Variable Fragments of Hybrid Logics
Hybrid logics extend modal logics by first-order concepts, in particular they allow a limited use of variables. Unfortunately, in general, satisfiability for hybrid formulas is u...

Properties of logics of individual and group agency
We provide proof-theoretic results about deliberative STIT logic. First we present STIT logic for individual agents without time, where the problem of satisfiability has recently b...

Classifying Descents According to Equivalence mod k
In [5] the authors refine the well-known permutation statistic "descent" by fixing parity of one of the descent's numbers. In this paper, we generalize the results o...
