... This is a modified form of Gauss-Newton s method, called Levenberg-Marquardt (LM) method. A relaxation parameter 1 64 is added to slow the update each iteration to ensure stability of = (1 1 + 1 51 the solution vector. The parameter solution vector is 3 x 1 in size for this study, 11 + ( 1 51 ) ) 1 2 + (210 (2.18...

... declare this hypercube to be generation 0. GAPS IMPLEMENTATION IN DETAIL: THE PARTITIONING SCHEME At any major iteration of the GAPS algorithm, a subset of the hypercubes will be selected as candidates for further sub-partitioning. At the initial step, only the hypercube surrounding the entire space...

... that determine the basic network structure and operation. It is our main objective to examine the overall structure of an iterative formulation of the problem of transient optimisation of networks, and then decide on its partition whether it be according to time or space. However, owing to the complexity...

... is known. So h3.Q3+hi.Qi +(hi*-hi)Qi= hs.D2 This is correct, but does is bring us any further ? Hold on. Suppose Qi is a fraction of the point flow upstream : Qp. In this case this is the flow through pipe 1. Let f be the fraction then : Qi = f.Qp . This fraction will not change to much between iterations...
