Jiujitsu is a highly technical martial art that relies on a deep understanding of various positions, which can be effectively organized as nodes in a directed graph. Transitions between these positions occur with success probabilities: representing the offensive player’s progression and representing the defender’s successful resistance. Taking this idea further, jiujitsu can be modeled as a Markov Chains, forming a graph symmetric around a set of 50/50 neutral positions, with terminal absorbing states corresponding to submissions that mark the end of the match. With this representation, you could even formulate it as a strategic game… but more on that later.”
