Design Optimization Landscape

  • How consciously do we navigate this?
    • Knowledge vs Prototyping
    • Width vs Depth of exploration
    • Speculation is "fast" to move but with uncertainty
    • Application focuses and finds new constraints, but it's expensive
  • Multidimensional and Multiobjective
  • Fuzzy/Noisy, Changing over time
  • We are all optimizers
    • We keep a model of the design landscape, updated by information (experiments, knowledge). Biased by our psychology
    • We try to "sample" promising areas to find a good solution
    • Similar to Bayesian Optimization (information directed sampling)
Bayesian Optimization. Used in black-box problems that
have a high sampling (evaluation) cost.
