How can we include subjective factors in algorithmic design?

In the competitive world of road race cycling, where winning may come down to a 1 percent advantage in power or speed, having a frame that is lighter and more aerodynamic grants a significant competitive advantage. Riders tend to be biased against metal-alloy frames, mostly because they assume they will be heavier than carbon options. To overcome this bias, a new bicycle frame was designed with topology optimization software, a special method that reduces the weight of a design by taking into account material properties and a fixed set of loads. However, the resulting design must also not appear fragile in the user’s subjective evaluation. With strategic edits to the algorithmic design recommendations, the HONE bicycle frame balances this tension.
