Artificial Immune Systems [PDF]

Search Methodologies: Introductory Tutorials in Optimisation and Decision Support Techniques, 375-399, 2005, 2009
The biological immune system is a robust, complex, adaptive system that defends the body from foreign pathogens. It is able to categorize all cells (or molecules) within the body as self-cells or non-self cells. It does this with the help of a distributed task force that has the intelligence to take action from a local and also a global perspective ...
