Reinforcement learning gets optimal policy through trial-and-error and interaction with dynamic environment. Its properties of self-improving and online learning make reinforcement learning become one of most important machine learning methods. Against reinforcement learning has been 'curse of dimensionality' troubled by the problem the question, a method of heuristic contour list is proposed on the basis of relational reinforcement learning. The method can represent states, actions and Q-functions through using first-order predications with contour list. Thus advantages of Prolog list can be exerted adequately. The method is to combine logical predication rule with reinforcement learning. A new logical reinforcement learning-CCLORRL is formed and its convergence is proved. The method uses contour shape predicates to build shape state tables, drastically reducing the state space;Using heuristic rules to guide the choice of action can reduce choice blindness when the sample does not exist in the state space. The CCLORRL algorithm is used in the Tetris game. Experiments show that the method is more efficient.

The watermark is split into a set of shares and represented as a set of graphs, which are embedded into the program dynamically. Code obfuscating technique in the embedding phase was used. A novel scheme of dynamic data structure software watermarking is presented. This scheme can restore the watermark according to partial watermark shares and is very robust and stealthy.

Description Logics are formalisms for representing knowledge of various domains in a structured and formally well-understood way. Typically, DLs are limited to dealing with precise and well defined concepts. In this paper we first present a fuzzy extension of ALC and define its syntax and semantics. Then we devote to taking advantage of the expressive power and reasoning capabilities of fuzzy ALC by encoding flexible planning problems within the framework of fuzzy ALC. Both theory and experimental results have shown that our method is sound and efficient.

A model based on multilocus interaction of schizophrenia was designed. Using the program of MATLAB through a C-language interface, combined with Fisher's exact test, a total of 18 SNPs that came from 9 susceptibility genes of the cPLA2 and PNPLA8 family were analyzed to detect positive sites of schizophrenia in multilocus association analysis. Results show that 4 positive sites at rs3816533, rsl668589, rsl356410 and rs40848 were detected in 13 SNPs, which did not deviate from the Hardy-Weinberg equilibrium (P>0.05). The haplotype significance test of these positive sites indicates that 6 haplotypes passing through rs3816533, rsl668589, rsl356410 and 2 haplotypes passing through rs40848 are associated with schizophrenia.
