It seems that AIs are really good at finding counterexamples now. Even if progress by AIs in proving conjectures lags, it seems likely that AIs collectively will, in the next few years, find counterexamples to nearly all the Erdős (and othe

For the vertex biconnected components can you say how your implementation compares technically with Boost Graph library's `biconnected_components` and `articulation_points`? https://www.boost.org/library/latest&#x2

As someone who has been mitigating and managing chronic pain for 25 years, with respect IMO your expectation is unrealistic. There isn't a "solution" - you're looking at a life-long mitigation and management strategy tha

"fully constrained" means that there are no degrees of freedom left so that there are only a finite number of valid solutions, which are then consequently disconnected in the space of possible solutions. DCM then chooses one valid

Good luck guys! I watched the video on YT - hopefully will get around to trying the Fusion 360 add-in at some point. Does the current add-in use AI at all? What is your plan when, in the event of you getting some traction, Autodesk etc. co
