The authors show that a system of $m$ linear inequalities with $n$ variables, where each inequality involves at most two variables, can be solved in $\tilde{O}(mn^2)$ time (we denote $\tilde{O}(f)=O(f\polylog n\polylog m))$ deterministically, and in $\tilde{O}(n^3+mn)$ expected time using randomization. Parallel implementations of these algorithms run in $\tilde{O}(n)$ time, where the deterministic algorithm uses $\tilde{O}(mn)$ processors and the randomized algorithm uses $\tilde{O}(n^2+m)$ processors. The bounds significantly improve over previous algorithms. The randomized algorithm is based on novel insights into the structure of the problem.
