Bio-inspired computing is a field of study that abstracts computing ideas (data structures, operations with data, ways to control operations, computing models, etc.) from the living phenomena or biological systems such as evolution, cell, tissue, neural network, immune system and ant colony. The areas of bio-inspired computing include genetic algorithm, DNA and molecular computing, membrane computing, neural computing, artificial immune systems, swarm intelligence, etc. The 9th International Conference on Bio-inspired Computing: Theories and Applications (BIC-TA 2014) will be held on 16th—19th October, 2014, in Wuhan, China. The conference aims to provide a high-level international forum for researchers working in the field of bio-inspired computing to present their recent results and to exchange ideas. The conference invites researchers to contribute high-quality original research papers in any aspect of bio-inspired computing.
