To provide effective psychotherapy for culturally different patients, therapists need to attain cultural competence, which can be divided broadly into the 2 intersecting dimensions of generic and specific cultural competencies. Generic cultural competence includes the knowledge and skill set necessary to work effectively in any cross-cultural therapeutic encounter. For each phase of psychothera...

Heterogeneous Multi-Population Cultural Algorithm (HMP-CA) is a new class of Multi-Population Cultural Algorithms which incorporates a number of local Cultural Algorithms (CAs) designed to optimize different subsets of the dimensions of a given problem. In this article, various dimension decomposition techniques for HMP-CAs are proposed and compared. The concept of using a dimension decompositi...

Based on the dual structure of culture algorithm, a multi-population cooperative cultural algorithm is proposed by embedding the competition cooperative genetic algorithm into the population space of culture algorithm. In each sub-population, genetic algorithm is adopted. And its population size is adjusted in terms of population density so as to enhance the diversity. In belief space, each kin...

Optimization problems arise in many real-world applications. Cultural Algorithms are a class of computational models derived from observing the cultural evolution process in nature, compared with genetic algorithm the cultural algorithms have high convergence speed. Aiming at the disadvantages of basic cultural algorithms like being trapped easily into a local optimum, this paper improves the b...

The paper describes how a formal model of selfadaptation [Angeline, 1995] can be expressed in terms of Cultural Algorithms. A particular form of self-adaptation concerns the shifting of the representational bias used to described the set of learned beliefs within the Cultural Algorthms. A version of Cultural Algorithms with the ability to shift its representational bias was used to solve the Ro...

Social psychologists have used the replacement method to simulate cultural evolution in the laboratory, studying what happens when a group of people performing a task are gradually replaced by new members. We provide a formal analysis of the dynamics of cultural evolution by replacement under the assumption that the people involved are Bayesian agents. We use a connection to a statistical infer...
