Design of Polyphase Codes Using Simulated Annealing

Using simulated annealing to design good codes

A NNEAL, as defined in Webster’s New Collegiate Dictionary, means: 1) to heat (as glass) in order to fix laid-on colors, and 2) to heat and then cool (as steel or glass) usually for softening and making less brittle. The cooling stage of annealing is usually done slowly to reduce the number of defects in the crystal structure (as steel) and to minimize the potential energy stored in the molecul...

Simulated Annealing and Optimal Codes

Using Simulated Annealing to Design Interconnection Networks

Simulated annealing is a computational technique reported to give good results in coping with complex combinatorial problems. These problems usually consist of finding a global minimum of a cost function on a (large) set of states (also known as feasible solutions). In this paper we explore modifications to the standard simulated annealing method that we apply to the design of dense interconnec...

Lighting Design by Simulated Annealing

In this paper, we present a lighting design framework for glossy real objects, starting from the reflectance field of an object. Using existing digital imaging software, the lighting designer paints the desired illumination distribution on a photograph of an object. This painted-on illumination is used to determine the light intensities which produce a shading of the real object matching the de...

Split-Pipe Design of Water Distribution Network Using Simulated Annealing

In this paper a procedure for the split-pipe design of looped water distribution network based on the use of simulated annealing is proposed. Simulated annealing is a heuristic-based search algorithm, motivated by an analogy of physical annealing in solids. It is capable for solving the combinatorial optimization problem. In contrast to the split-pipe design that is derived from a continuous di...
