For transcriptional kinetic mechanism research, raising the accuracy of identifying model parameters is an important work. Usually, the training data we obtained are noisy and sparse. This paper uses the ordinary differential equation to model transcriptional regulation. Gaussian prior distribution is adopted to describe the unobserved transcriptional factors activity. The approximation of gene expression...
The Risk Budgeted Global Asset Allocation Portfolio problem strives to obtain an optimal portfolio of assets across global markets, with the objective of maximizing its Sharpe Ratio, subject to the constraints of risk budgets and other specific conditions imposed by the investors on the various asset classes comprising the portfolio. The mathematical formulation of the optimization problem turns out...
According to the response surface methodology (RSM), this paper proposes a new trial vector perturbation model for Differential Evolution(DE). It not only consists of linear and nonlinear heuristics for optimum exploring, but also retains simplicity style of DE mutation operator in appearance which can help the new algorithm absorb many existed elegant methods from a large amount of DE variants. The...
In this paper taking structure parameters as variables, and considering the mechanical restriction and temperature rise in it, we study the maximal force and minimal coil inductance. Based on fundamental of genetic algorithm (GA), we use its eximious character and associate with trait of Radial Bearing, Using dynamic programming, we construct mathematical model of Radial Bearing, thereby solve its...
The unidirectional logistics distribution vehicle routing problem with no time windows is considered. It contains the vehicle capacity restriction, the longest distance restriction and the full loaded vehicle. The solution must ensure the non-full loaded factor is the least and the total distance is the shortest. A multi-objective optimization mathematical model for the problem is established. And...
