ZOE (Zero One Equation)

Untitled

$\left[\begin{matrix} 1 & 0 \\ 0 & 1 \\1&0\end{matrix}\right] \times \left[\begin{matrix} x_1\\x_2\end{matrix}\right] = \left[\begin{matrix} 1 \\ 1 \\1\end{matrix}\right]$ A x 1

3D Matching → ZOE

Untitled

Therefore 3D matching problem reduced into ZOE problem

ZOE is NP-Complete

ZOE → Subset Sum

Given a set of integers, target W find subset of integers that sum = W

Therefore ZOE reduced into Subset Sum Problem

Subset Sum is NP-Complete

ZOE → ILP

ILP: Integer Linear Programming
