I may be reading this wrong, but I think this means that a shot glass is mathematically perfect.

I'd notice that this must also describe the best shape of a glass to keep a beverage hot . But, unlike shot glasses, tea and coffee cups look very different.

Perfect all depends on what you're optimizing for.

If you want a glass that doesn't tip over easily, this isn't so great.

Theory versus practice. The best entrepreneurs are able to see past the theory and grapple with practical considerations.

Awesome, but why a genetic algorithm? I wonder if it could be formulated as a tractable optimization problem instead.

Or perhaps solved more purely using Calculus of Variations.

that was my first thought too. we developers sometimes get so caught up in development weforget there's a whole world of other tools.

So put a stem on it:

I guess that the ratio h_open/h_closed is much bigger for hot beverages, due to evaporative cooling. Of course, this would mean that the optimum shape is even thinner than those that were calculated.

But maybe the shape of tee-cups and coffee mugs is optimal, in its own way? I certainly appreciate that beverages that need quite high temperatures for brewing are cooled down quickly to a drinkable temperature.

Interesting, this shape matches exactly the yogurt jars sold on the streets in Beijing. They need to remain cool without refrigeration for long periods of time.

Then they should be spherical; this shape's optimal only for a container which is gradually emptying.

Take this shape, minimize thermal conductivity to its surroundings but enable it to stand safely on a flat surface, and what you have got is a stemmed wine glass.
