Interior point and newton methods in solving high dimensional flow distribution problems for pipe networks

... Lecture Notes in Bioinformatics). Vol.10556 LNCS. 2017. P.139-149. ISBN (print): 9783319694030. DOI: 10.1007/978-3-319-69404-7_10 In this paper optimal flow distribution problem in pipe network is considered. The investigated problem is a convex sparse optimization problem with linear equality and inequality constrains. Newton method is used for problem with equality constrains only and obtains an approximate solution, which may not satisfy inequality constraints. Then Dikin Interior Point Method starts ...

Search for feasible solutions by interior point algorithms

... Vol.9. No.3. 2016. P.191-206. DOI: 10.1134/S1995423916030022 A family of interior point algorithms for linear programming problems is considered. In these algorithms, entering the feasible solution region of the original problem is presented as an optimization process of an extended problem. This extension is performed by adding a new variable. The main objective of the paper is a theoretical justification of the procedure of entering the feasible region of the original problem under the assumption ...
