descent in input space you can optimize the shape so as to get the properties you want on the output which you you know you can't really do it with a regular computational fluid dynamics piece of code so it's really interesting he actually has a startup that works on this yes huh well I guess you have to really know the underlying physics to be able to make that generalization so I mean you can test on relatively small spatial domain because you can run the PD solver so you know how accurate your new ComNet is the
