FAdo is an ongoing project which aims to provide a set of tools for symbolic manipulation of formal languages. To allow highlevel programming with complex data structures, easy prototyping of… (More)
Memetic algorithms are highly efficient procedures to solve complex optimization problems. They combine strengths of well known metaheuristics, like the genetic algorithm (GA), with local search (LS)… (More)
GUItar is a visualization software tool for various types of automata (standard, weighted, pushdown, transducers, Turing machines, etc.). It provides interactive manipulation of diagrams,… (More)
We present an interactive graphical environment for the manipulation of context-free languages. The graphical environment allows the editing of a context-free grammar, the conversion to Chomsky… (More)
The several aspects on the chemistry of eremanthine such as isolation, structural classification, biological activity, synthesis, and chemical transformations in other sesquiterpene lactones are… (More)
This paper reports an overview on the chemistry of the indole alkaloid goniomitine focusing, mainly, on the methods of synthesis related to this natural product and analogs.
