In order to model multi-dimensions and multi-granularities oriented complex systems. this paper firstly proposes a kind of multi-relational Fuzzy Cognitive Map (FCM) to simulate the multi-relational system and its auto construct algorithm integrating Nonlinear Hebbian Learning (NHL) and Real Code Genetic Algorithm (RCGA). The multi-relational FCM fits to model the complex system with ... https://trendingcustomes.shop/product-category/acrylic-heart-plaque/
