This book provides the first computer simulation book for non-programmers and non-scientists. This meets the growing demand on the digital shelf for those who need to use or design simulations and those who are part of a design team building a sim or a game. Authored by two of the most pre-eminent experts in the field of computer simulation, the coverage provides readers with what they need to understand the simulations they fund, build, or use without having to earn another degree. Includes online ancillary materials.
