Association of the Hemoglobin–Albumin–Lymphocyte–Platelet (HALP) Score with 3-Month Outcomes After Lumbar Medial Branch Radiofrequency Ablation: A Retrospective Cohort Study [PDF]
DiagnosticsBackground: The hemoglobin–albumin–lymphocyte–platelet (HALP) score integrates the immunonutritional and inflammatory status. We evaluated whether baseline HALP predicts the 3-month response after lumbar medial branch radiofrequency ablation (RFA ...

Solving Linear Integer Models with Variable Bounding
Forecasting, 2023 We present a technique to solve the linear integer model with variable bounding. By using the continuous optimal solution of the linear integer model, the variable bounds for the basic variables are approximated and then used to calculate the optimal ...

Parameters of finger stalk lifter cut branches in intensive gardens [PDF]
E3S Web of Conferences, 2023 In Uzbekistan, the areas of intensive orchards are expanding, in which branches are regularly pruned according to agrotechnical rules. In intensive orchards, the number of fruit trees is usually greater, so cut branches occupy most of the row-spacing ...

An abstract model for branch and cut
Mathematical Programming, 2022 Branch and cut is the dominant paradigm for solving a wide range of mathematical programming problems -- linear or nonlinear -- combining efficient search (via branch and bound) and relaxation-tightening procedures (via cutting planes, or cuts).

Branch-and-cut solution approach for multilevel mixed integer linear programming problems
EURO Journal on Computational Optimization, 2023 A multilevel programming problem is an optimization problem that involves multiple decision makers, whose decisions are made in a sequential (or hierarchical) order. If all objective functions and constraints are linear and some decision variables in any

Solving the Traveling Salesman Problem with release dates via branch and cut
EURO Journal on Transportation and Logistics, 2023 In this paper we study the Traveling Salesman Problem with release dates (TSP-rd) and completion time minimization. The TSP-rd considers a single vehicle and a set of customers that must be served exactly once with goods that arrive to the depot over ...
