Constrained constructive optimization (CCO) is a commonly used algorithm for vascular simulation, particularly well known for its adaptability toward vascular modeling across tissues. The present work demonstra
1) constrained constructive optimization 强制结构优化1. Referring to the method of constrained constructive optimization(CCO),a new method based on bifurcation law,Poiseuille’s law and mass conservation was proposed to model arterial trees directly in simulation objects. 进行血液动力学模拟和血液传热...
1 and 2, the performance of the PSO-DE is better than the PSO and DE on the testing suite in terms of the optimization results. PSO converges to local optima quickly and the particles give up attempts for exploration. Then the PSO stagnates in the rest of evolution. Due to DE, PSO-...
In the seminal work [2], the authors considered the noiseless setting and proposed the following optimization problem to recover x*minx∈Rn∥x∥1,s.t.y⊙Ψx≥0,and∥x∥2=1,where “⊙” and “≥” denote the Hadamard product and element-wise inequality, respectively. [11] also considered...

The last decade of phylogenetics has seen the development of many methods that leverage constraints plus dynamic programming. The goal of this algorithmic technique is to produce a phylogeny that is optimal with respect to some objective function and tha
It can be used to declare and define the elements of an optimization model such as variables, parameters, objective function, and constraints. The exploration of the search space is completely done in a proprietary black-box fashion by LocalSolver. In principle, it is possible to use a direct...
(grant. 41274052 & 41474033), Academician Workstation Construction of Yunnan Province (No. 2014IC007). We appreciate Prof. B. Meade for making his block modelling program available. Many thanks go to Prof. Shiming Wang for his very constructive suggestions. Finally, I want to give my thanks ...
Next we turn to the optimization of the dual function (25) over and . First we consider the optimization over for fixed to find. We differentiate (25) with respect to and set the derivative to 0 to obtain (26) The optimum is derived from (26) as follows: ...
This special variant of a multi-objective optimization problem considers the total number of required trucks as main objective dominating all other goals due to the high cost of labor. However, after fixing the overall number of trucks (and thus the number of required personal) secondary ...
