Watched Eric Demaine's lecture and initially did not understand the reduction from 3-SAT to 3-dimensional matching.

16. Complexity: P, NP, NP-completeness, Reductions https://youtu.be/eHZifpgyH_4?t=2786

Goal

To reduce 3-SAT to 3DM, we need to show how to express every 3-SAT problem as a 3DM problem. If 3DM has a solution, then that solution can be applied to solve any 3-SAT problem.

Consider the following problem:

A Water Jug Problem:

    You are given two jugs, a 4-gallon one and a 3-gallon
    one, a pump which has unlimited water which you can use
    to fill the jug, and the ground on which water may be
    poured. Neither jug has any measuring markings on it.
