  • Publication number: 20060225003
    Abstract: A design system includes a design engine for generating designs, an evaluation process for evaluating the generated designs based on human visual inspection and/or domain knowledge, and an optimization process for pruning based at least in part on the evaluation. Generation of additional designs is performed based on optimization. Newly-generated designs are then subjected to the same iterative steps. In one embodiment a simulator is also used to evaluate the generated designs, in part, with numerically designed specification. Subjective human evaluation is used fully or at least in part of an optimization process to obtain final designs. Human visual inspection and domain knowledge is used to evaluate and rate key designs at different points in the evolution of a design.

  • Patent number: 6148274
    Abstract: At the start of a process, an information presenting section presents information expressed by a solution vector, while an auxiliary information presenting section presents information for facilitating comparative evaluation of multiple pieces of information being presented simultaneously. Based on these pieces of information, the user evaluates each solution vector. A model estimation executing section generates an evaluation model for an adjustment process from a user evaluation history, and thereafter, a model evaluation calculating section performs evaluation using the evaluation model. A fitness calculating section calculates fitness from the evaluation made by the user or by the model, and in accordance with the thus calculated fitness, a recombination operation section performs an arithmetical recombination operation. The above process is iteratively performed to carry out optimum adjustment of solution vectors.
