Primal

Primal refers to the fundamental or most basic level of something. In various fields like mathematics, optimization, or science, it typically denotes the original problem or structure from which others are derived or related. For example, in optimization, the primal problem is the original formulation that seeks to find the best solution under certain constraints, while related concepts like the dual problem provide alternative perspectives. Understanding the primal helps clarify the core objectives and constraints of a system before exploring more complex or derived formulations, making it essential for solving and analyzing problems efficiently.
