## Abstract

We present two randomized algorithms. One solves linear programs involving*m* constraints in*d* variables in expected time*O(m)*. The other constructs convex hulls of*n* points in ℝ^{d},*d*>3, in expected time*O(n*^{[d/2])}. In both bounds*d* is considered to be a constant. In the linear programming algorithm the dependence of the time bound on*d* is of the form*d*!. The main virtue of our results lies in the utter simplicity of the algorithms as well as their analyses.
