Function-based cost estimating
International Journal of Production Research, 2008 Communication between cost estimators with commercial (CE-C) and engineering (CE-E) backgrounds is essential for good internal practice. This paper presents a Function-Based Cost Estimating (FUCE) framework to link the commercial and engineering communities through a structured approach at the conceptual design stage.

Multiobjective Fitness Functions With Nonlinear Switching for Antenna Optimizations
IEEE Open Journal of Antennas and Propagation, 2022 In a multi-objective optimization process, several goals are traditionally combined into a single fitness function. In such cases, the choice of the objective function is critical, as it should accurately represent the desired optimization goals.

Searching for cost functions [PDF]
Proceedings of the 2004 Congress on Evolutionary Computation (IEEE Cat. No.04TH8753), 2005 Boolean function design is at the heart of cryptography, and is the subject of a great deal of theoretical research. We have use a simulated annealing approach to find functions with particular desirable cryptographic properties; for functions of a small number of variables, results with properties as good as (and sometimes better than) the best so far
