Experimental researches of interior-point algorithms for solution of flow distribution nonlinear problems

The results of experimental researches of direct and dual interior point algorithms with different methods of specifying weight coefficients in nonlinear problems of flow distribution are given. The experiments have revealed the advantage of linear weight coefficients, divided by the Lagrange multipliers, in comparison with the quadratic ones. It has been found out that the required accuracy of solution is attained faster when using the dual algorithm, than when using direct algorithm.
