Abstract
Given a triangle in the plane, a planar convex compact set and an upper and and a lower bound, we
derive a linear programming algorithm which checks if there exists a real-valued Lipschitz map defined
on the triangle and bounded by the lower and upper bounds, whose Clarke subgradient lies within the
convex compact set. We show that the problem is in fact equivalent to finding a piecewise linear surface
with the above property. We extend the result to a convex quadrilateral in the plane. In addition, we
obtain some partial results for this problem in higher dimensions.
