On a problem of optimal search
Zeitschrift für Operations Research, 1977 A class of one-dimensional search problems is considered. The formulation results in a functional-minimization equation of the dynamic programming type. In the case of a uniform a priori distribution for the location of the hidden object an optimality criterion is established and the optimal search procedure is found.

Two approaches toward constrained vector optimization and identity of the solutions [PDF]
In this paper we deal with a Fritz John type constrained vector optimization problem. In spite that there are many concepts of solutions for an unconstrained vector optimization problem, we show the possibility “to double” the number of concepts when a ...

Design optimization based on state problem functionals
, 2015 This paper presents a general mathematical structure for design optimization problems, where state problem functionals are used as design objectives.It extends to design optimization the general model of physical theories pioneered by Tonti (1972, 1976 ...

Optimization of the Production of Rubber Compounds Using Mathematical Models
Advanced Engineering Materials, EarlyView.Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Learning and Intelligent Optimization. 4th International Conference LION 4
, 2010 In the design of complex engineering systems involving multiple disciplines it is critical that the interactions between the subsystems of the problem are accountedfor. Only by considering the fully coupled system can an optimal design emerge.

Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

An optimization problem on graphs
Discrete Applied Mathematics, 1986 A graph G with vertex set \(X=\cup^{n}_{i=1}X_ i\), for n given sets \(X_ i\), is called a feasible graph for \((X_ 1,...,X_ n)\) if, for each \(X_ i\), the subgraph \(G_ i\), with vertex set \(X_ i\), is connected. The authors consider the (NP-hard) problem of finding a minimum feasible graph.

Advanced Engineering Materials, EarlyView.This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.
