✦ Synopsis


We present an algorithm for solving the problem of globally minimizing a concave function over the integers contained in a compact polyhedron. The objective function of this problem need not be separable or even analytically defined. To our knowledge, the algorithm is the first ever proposed for this problem. Among the major advantages of the algorithm are that no nonlinear computations or optimizations are required, and that it allows one to exploit the polyhedral nature of X . We discuss these and other advantages and disadvantages of the algorithm, and we present some preliminary computational experience using our computer code for the algorithm. This computational experience seems to indicate that the algorithm is quite practical for solving many concave integer minimization problems over compact polyhedra.

## Abstract One of the main challenges for protein redesign is the efficient evaluation of a combinatorial number of candidate structures. The modeling of protein flexibility, typically by using a rotamer library of commonly‐observed low‐energy side‐chain conformations, further increases the comple
