Tests quadratic programming

Successive Quadratic Programming (SQP) The above approach to finding the optimum is called a feasible path method, as it attempts at all times to remain feasible with respect to the equahty and inequahty constraints as it moves to the optimum. A quite different method exists called the Successive Quadratic Programming (SQP) method, which only requires one be feasible at the final solution. Tests that compare the GRG and SQP methods generaUy favor the SQP method so it has the reputation of being one of the best methods known for nonlinear optimization for the type of problems considered here. [Pg.486]

Results were analyzed by nested mixed-model ANOVA s using general linear procedures, in the MINITAB 15 statistical program. Nested mixed-model ANOVA was used when multiple leaves per tree and multiple trees per treatment were available. Additional analyses were linear and quadratic regressions (performed in MINITAB 15 and Excel), and when significant differences occurred, means were compared using Student s t-test or nested mixed-model ANOVA. [Pg.240]

Anyway, the first step toward any receptor-based COSMO-RS calculations is the calculation of qualitatively acceptable er-profiles of the receptor regions of enzymes. In a performance test of a highly parallel version of the TURBOMOLE program on the supercomputer at the Research Center Jiilich [141], we could show that TURBOMOLE presently can handle single point, i.e., fixed geometry, BP-SVP DFT-calculations of enzymes up to about 1,500 atoms. On the basis of preliminary data, an enzyme of 1,000 atoms requires about 6 CPU h on 32 CPUs of a supercomputer cluster with a minimum quadratic scaling of CPU-time with the number of atoms of the enzymes. Thus for medium-sized enzymes we would require a minimum of 600 h on such a supercomputer, which would be rather expensive, even if all the technical problems arising at these molecule sizes would be solved. Therefore, brute-force DFT calculations appear to be unfeasible at present, but they may be possible in the future. [Pg.194]

NPPC [22] is a binary classifier and it classifies a pattern by the proximity of a test pattern to one of the two planes as shown in Fig. 5. The two planes are obtained by solving two nonlinear programming problems (NPP) with a quadratic form of loss function. Each plane is clustered around a particular class of data by minimizing sum squared distances of patterns from it and considering the patterns of the others class at a distance of 1 with soft errors. Thus, the objective of NPPC is to find two hyperplanes ... [Pg.150]
