While the dynamics of many complex systems is dominated by activated events, there are very few simulation methods that take advantage of this fact. Most of these procedures are restricted to relatively simple systems or, as with the activation-relaxation technique (ART), sample the conformation space efficiently at the cost of a correct thermodynamical description. We present here an extension...

Origami is the centuries-old art of folding paper, and recently, it is investigated as computer science: Given an origami with creases, the problem to determine if it can be flat after folding all creases is NP-hard. Another hundreds-old art of folding paper is a pop-up book. A model for the pop-up book design problem is given, and its computational complexity is investigated. We show that both...

We introduce positive-only projection (PoP), a new algorithm for constructing semantic spaces and word embeddings. The PoP method employs random projections. Hence, it is highly scalable and computationally efficient. In contrast to previous methods that use random projection matrices R with the expected value of 0 (i.e., E(R) = 0), the proposed method uses R with E(R) > 0. We use Kendall’s τb ...

Współcześnie próby systematyzowania sztuki na podstawie jej wartości zastępują raczej teorie opisowe, które stronią od ocen. Co więcej, refleksja postmodernistyczna, zmieniając swój stosunek do niskiej, skutecznie zatarła różnice w hierarchizacji walentnych treści sztuki. Wzmocnienie głoszonych awangardzie programowych tez zmierzających unieważnienia dotychczasowych kryteriów postaw oceniającyc...
