A dual exterior point simplex type algorithm for the minimum cost network flow problem

Autor: Geranis George, Paparizzos Konstantinos, Sifaleras Angelo

Publikováno v: Yugoslav Journal of Operations Research, Vol 19, Iss 1, Pp 157-170 (2009)

A new dual simplex type algorithm for the Minimum Cost Network Flow Problem (MCNFP) is presented. The proposed algorithm belongs to a special 'exterior- point simplex type' category. Similarly to the classical network dual simplex algorithm (NDSA), t

Dynamic trees in exterior-point Simplex-type algorithms for network flow problems

Autor: George Geranis, Angelo Sifaleras

Publikováno v: Electronic Notes in Discrete Mathematics. 41:93-100

Recently, a new Dual Network Exterior-Point Simplex Algorithm (DNEPSA) for the Minimum Cost Network Flow Problem (MCNFP) has been developed. In extensive computational studies, DNEPSA performed better than the classical Dual Network Simplex Algorithm

On a dual network exterior point simplex type algorithm and its computational behavior

Autor: Konstantinos Paparrizos, Angelo Sifaleras, George Geranis

Publikováno v: RAIRO - Operations Research. 46:211-234

The minimum cost network flow problem, (MCNFP) con- stitutes a wide category of network flow problems. Recently a new dual network exterior point simplex algorithm (DNEPSA) for the MCNFP has been developed. This algorithm belongs to a special "exteri
