This paper presents an evolutionary approach to searching for cellular automata that accept gliders. The proposed technique is based on a specific fitness function taking into account spatial evolution, the number of living cells, and the presence of gliders. The results show that the genetic algorithm is a promising tool for finding cellular automata with… (More)
We use a stochastic local search based method to build SAT instances that are diicult for a given stochastic local search algorithm 2. This principle can be extended to the production of SAT instances with other unusual features.
The authors recall that early diagnosis and treatment are essential if cure without sequelae is to be obtained. The principle of treatment is based on two essential phases : heparinization (with continuous infusion), antivitamins K, which follow on. Several products, known empirically, may be used in addition, either during the acute phase (hydergine,… (More)
