Genetic programming approach to determining of metal materials propertiesBrezočnik, Miran ; Balič, Jože ; Kuzman, Karl, 1941-2022The papers deals with determining metal materials properties by use of genetic programming (GP). As an example, the determination of the flow stress in bulk forming is presented. The flow stress can ... be calculated on the basis of known forming efficiency. The experimental data obtained during pressure test serve as an environment to wich models for forming efficiency have to be adapted during simulated evolution as much as possible. By performing four experiments, several different models for forming efficiency are genetically developed. The models are not a result of the human intelligence but of intelligent evolutionary process. With regard to their precision, the successful models are more or less equivalent; they differ mainly in size, shape, and complexity of solutions. The influence of selection of different initial model components (genes) on the probability of successful solution is studied in detail. In one especially successful run of the GP system the Siebel's expression was genetically developed. In addition, redundancy of the knowledge hidden in the experimental data was detected and eliminated without the influence of human intelligence. Researches showed excellent agreement between the experimental data, existing analytical solutions, and models obtained genetically.Source: Journal of intelligent manufacturing. - ISSN 0956-5515 (Vol. 13, no. 1, 2002, str. 5-17)Type of material - article, component partPublish date - 2002Language - englishCOBISS.SI-ID - 46938881
