Triangulation (geometry) | NP-hard problems | Computer-assisted proofs
In computational geometry and computer science, the minimum-weight triangulation problem is the problem of finding a triangulation of minimal total edge length. That is, an input polygon or the convex hull of an input point set must be subdivided into triangles that meet edge-to-edge and vertex-to-vertex, in such a way as to minimize the sum of the perimeters of the triangles. The problem is NP-hard for point set inputs, but may be approximated to any desired degree of accuracy. For polygon inputs, it may be solved exactly in polynomial time. The minimum weight triangulation has also sometimes been called the optimal triangulation. (Wikipedia).

440-pound Deadlift: First Lift 2x Bodyweight
I weigh 220 pounds so this 440-pound deadlift is my first ever of twice my bodyweight and a new all-time PR. My previous PR was 405 pounds in May 2021; delighted to crush that figure a year later :)
From playlist Weightlifting
This morning I set a one-rep-max personal record for the deadlift: 405 pounds, which is my first-ever lift over 400 pounds and ranks me at the 72nd percentile among male CrossFitters. This is a wide margin over previous PRs of 365 lb. (May 13th) and 315 lb. (December 2019).

Petar Pavešić (9/1/21): Category weight estimates of minimal triangulations
When one applies computational methods to study a specific manifold or a polyhedron it is often convenient to have as small triangulation of it as possible. However there are certain limitations on the size of a triangulation, depending on the complexity of the space under scrutiny. The de
