The minimum cut and maximum flow problems form a well-known pair of dual problems providing a min-max relation. Similarly, the continuous relaxation of the minimum multicut problem is the linear dual ...

We present an algorithm that computes exact maximum flows and minimum-cost flows on directed graphs with m edges and polynomially bounded integral demands, costs, and capacities in m 1+o(1) time. Our ...

We employ signed measures that are positive definite up to certain degrees to establish Levenshtein-type upper bounds on the cardinality of codes with given minimum and maximum distance, and universal ...

Keywords: minimum backbone grid, mixed integer linear programming, connectivity constraints, single-commodity flow, resilience. Citation: Mei W, Sun Z, He Y, Liu M, Gong X and Li P (2023) A mixed ...

CBSE Class 12th Linear Programming Revision Notes: ... If R is bounded**, then the objective function Z has both a maximum and a minimum value on R and each of these occurs at a corner point ...
