that uses simultaneous convexification. We introduce a separation method that relies on determining the convex envelope of …

We study the double discrete Legendre–Fenchel transform (LFT) to approximate the convex envelope of a given function … has great impact on the accuracy of the resulting approximation of the convex envelope. Then, we present an improvement …

In this work we derive explicit descriptions for the convex envelope of nonlinear functions that are component … nonlinearities in common benchmark libraries. To overcome the combinatorial difficulties in deriving the convex envelope description … given by the component-wise concave part of the functions, we consider an extended formulation of the convex envelope based …
