Vectors i and j form a unit square, and span 2D space. Drag and drop i' and j' to scale, rotate, and flip the unit square, and 2D space- so that the blue point falls on the red. Click solve to see how to get a (non unique) solution, and help for more intuition.
Find the BasisYou are the blue point trying to catch the red. Every move, a random edge is removed. Try to corner the red point before an edge is removed and the points are separated. Switch to defense mode to try and evade red, and switch to two players to play with a friend.
Catch the PointThe red points are students, and the blue points are Universities. The edge weights represent how well each student would fit at each University. Highlight the set of edges that maximize the score for everyone involved. Press check to see if your matching is optimal.
Graph the MatchChallenge yourself with classic games Tic Tac Toe, Connect 4 and Snake, this time in three dimensions.
The goal is to promote one of your peices to the opposite end of the board before your opponent. Every move, a triangle can move one square up, down, left or right. Land on an opposing triangle to capture it. Try to find a path to victory while blocking your opponent.
