DIRECTLib - a library of global optimization problems for DIRECT-type methods

<strong>DIRECTLib - a library of a box and generally-constrained global optimization problems for DIRECT-type methods</strong> In this library, we present the collection of a box and generally constrained global optimization test problems (in MATLAB format) typically used to test various DIRECT-type [1] methods in the relevant literature (see, e.g., [2-4] and references given therein). <strong>References</strong> Jones, D.
