Abstract This thesis develops an Algol computer model (simulator) of the IHAS-4 airborne digital computer. The simulator is used as a tool in debugging machine language computer programs and in evaluating the relative efficiency of computer hardware alternatives in meeting requirements based upon relative speed and memory specifications. The simulator consists of a memory, an input/output section, a set of routines corresponding to the set of instructions for the IHAS-4 computer, and a...

Abstract The purpose of this paper is to investigate the suitability of dynamic simplex search methods for finding the global extremum of multimodal functions. The search will be in N variable space with the form of the function unknown or in such a form that conventional techniques such as the calculus cannot be used. The initial search is conducted using the dynamic simplex method to find the first extremum. Three methods were evaluated for their usefulness in determining the global...
