Variable propagation is a powerful technique in programming and algorithms. It optimizes performance by reducing unnecessary recalculations and improving overall efficiency. This concept refers to passing known variable values across various components of an algorithm, i.e. “propagating” the values of variables so that they can be reused whenever needed, without recomputing them.
