I sometimes forget whether you flip the rotate the matrix by 180° or mirror it on an axis when I didn't do any linear algebra for a while. However, that doesn't happen too often lately. I guess it's easier to remember if you see it visualised like that.

It's based on mass and luminosity. Red supergiants can be smaller than blue hypergiants. There's a big explanation but tl;dr it's based off a function of energy emitted per unit time per area, mass of the star, and planck's law.

Generally, the hotter you get, the more luminous you are, the bluer you get, and your radius doesn't increase as much as your mass. However, cooler stars are redder, they have less luminosity, and their radius increases far more than their mass.

Hertzsprung-Russell diagrams really explain this.

It's Dijkstra's algorithm to find the shortest path between two nodes on a graph. Basically as long as the cost to move between nodes is never negative, you can always just choose to continue along the current shortest path until you reach the goal node. It is an example of a greedy algorithm because repeatedly taking the locally optimal choice leads to the correct solution.
