The 2-SAT Problem of Regular Signed CNF Formulas
Signed conjunctive normal form (signed CNF) is a classical conjunctive clause form using a generalized notion of literal, called signed atom. A signed atom is an expression of the...

NFA Reduction Algorithms by Means of Regular Inequalities
We present different techniques for reducing the number of states and transitions in nondeterministic automata. These techniques are based on the two preorders over the set of st...

A Cost-Regular Based Hybrid Column Generation Approach
Abstract. Constraint Programming (CP) offers a rich modeling language of constraints embedding efficient algorithms to handle complex and heterogeneous combinatorial problems. To s...

Exact Covariance Thresholding into Connected Components for Large-Scale Graphical Lasso
We consider the sparse inverse covariance regularization problem or graphical lasso with regularization parameter λ. Suppose the sample covariance graph formed by thresholding th...

The Generalization of Generalized Automata: Expression Automata
Abstract. We explore expression automata with respect to determinism, minimization and primeness. We define determinism of expression automata using prefix-freeness. This approac...
