  abstract =     "The optimal material processing in steel industry is
                 difficult because of the multi-constituent and
                 multiphase character of the commercial steels, variety
                 of the possible processing paths, and plant specific
                 equipment characteristics. This paper shows
                 implementation of the genetic programming approach for
                 crack presence modelling after rolling. The data (110
                 samples covering 7 different steel grades) on diffusive
                 annealing, last pass rolling temperature, chemical
                 composition of steel (weight percent of Mn, Cr, Mo and
                 V), steel bar dimensions (width and thickness), heating
                 time of the first and the last batch billet were
                 collected during daily production. The manual
                 ultrasound method was used for crack detection. On the
                 basis of the monitored data a mathematical model for
                 crack presence was developed by genetic programming.
                 For the modeling it was adopt that after the rolling
                 the material was treated equally. The modelling results
                 assume that the material processing after rolling is
                 probably very influential on crack occurrence.",
