This ebook offers with the idea and purposes of the Reformulation- Linearization/Convexification approach (RL T) for fixing nonconvex optimization difficulties. A unified remedy of discrete and non-stop nonconvex programming difficulties is gifted utilizing this method. In essence, the bridge among those forms of nonconvexities is made through a polynomial illustration of discrete constraints. for instance, the binariness on a 0-1 variable x . may be equivalently J expressed because the polynomial constraint x . (1-x . ) = zero. the incentive for this e-book is J J the position of tight linear/convex programming representations or relaxations in fixing such discrete and non-stop nonconvex programming difficulties. The critical thrust is to begin with a version that provides an invaluable illustration and constitution, after which to extra enhance this illustration via computerized reformulation and constraint iteration options. As pointed out above, the focus of this booklet is the advance and alertness of RL T to be used as an automated reformulation strategy, and in addition, to generate robust legitimate inequalities. The RLT operates in stages. within the Reformulation part, specific sorts of extra implied polynomial constraints, that come with the aforementioned constraints relating to binary variables, are appended to the matter. The ensuing challenge is as a consequence linearized, other than that sure convex constraints are often retained in XV specific specified instances, within the Linearization/Convexijication part. this is often performed through the definition of compatible new variables to switch each one specific variable-product time period. the better dimensional illustration yields a linear (or convex) programming rest.
