We present a fuzzy model of P systems where the objects involved in computations are colored by means of a finite family of fuzzy sets, and we discuss several applications of this model in computational biology.

We revisit the FAM algorithm with the aim of clarifying the inner working of the algorithm with respect to implementing it. We provide a step through the original presentation, clarifying issues that are of interest to implementors of the specific algorithm as well as to implementors of other EM algorithms in PLP frameworks. In addition, this paper presents Pepl, an implementation of the algori...

By fuzzifying the number of occurrences of an element of a multiset, we obtain a new fuzzy structure; similarly, by fuzzifying the number of occurrences of an element of a hybrid set, we obtain another new fuzzy structure. The aim of the present work is twofold: to provide a concise definition of these new fuzzy structures and their properties and to apply them in natural computing. More specif...
