We describe origami programming methodology based on constraint functional logic programming. The basic operations of origami are reduced to solving systems of equations which desc...
In this paper we investigate the addition of arbitrary independent involutive negations to t-norm based logics. We deal with several extensions of MTL and establish general comple...
We present an encoding that is able to specify LTL bounded model checking problems within the Bernays-Sch?onfinkel fragment of first-order logic. This fragment, which also correspo...
This paper describes in detail the combination of NLP methods applied to the treatment of logic forms in the topic processing and statistical methods applied to the search engine ...
