We constantly make decisions which are simply "good enough" rather than optimal—a type of decision for which Wynn Stirling has adopted the word "satisficing". Most computer decision making algorithms, however, seek only the optimal solution based on rigid criteria and reject others. Outlining an alternative approach, this book uses novel algorithms and techniques to more closely model the way humans make decisions. It is, therefore, of interest to engineers, computer scientists and mathematicians working on artificial intelligence and expert systems.
