constrained problem meaning in English
[数] 约束问题
Examples
- the over-constrained and under-constrained problem can be solved naturally in our approach because that a constraint problem is transformed into an optimal problem does n't entail that the number of constraint equations equal to the one of constraint variables
由于将约束问题首先转化为优化问题的过程中，并没有要求约束变量的数目与约束的数目相等，因此可以自然地求解欠约束问题和过约束问题。 - abstract firstly, convert a programming problem with multiple constraints into a programming problem with single constraint, secondly, several convexification and concavification transformations for the constrained problem with strictly monotone constraint functions are proposed according to the transformed problem with single constraint, then this constrained programming problem can be converted into a concave minimization or a reverse convex programming problem
摘要首先将一个具有多个约束的规划问题转化为一个只有一个约束的规划问题，然后通过利用这个单约束的规划问题，对原来的多约束规划问题提出了一些凸化、凹化的方法，这样这些多约束的规划问题可以被转化为一些凹规划、反凸规划同题。 - one of constrained problem is delay constrained steiner tree problem . a heuristic dbma ( delay-bounded multicast routing algorithm ) based on minimum delay path set and minimum cost path set is proposed . simulation result demonstrate that it is a delay constrained algorithm with low time complexity and low cost
首先是时延约束的最小steiner树问题，在比较了现有的算法以后，提出了一种基于最短时延路径集和最小费用路径集的多播路由算法??dbma算法，仿真结果表明该算法是一种低复杂度的时延约束低费用多播路由算法。 - based on a great many literature, this paper analyzes and summarizes the genetic algorithm for the design of structural optimization . the basic conceptions and primary characteristics are introduced in this paper . this paper discuss some primary factor when genetic algorithm applied on optimal design, for example the mathematical model 、 the constrained problem 、 the initial population and the controls parameter of genetic algorithm aimed at the characteristic of structural optimization and finite-element analysis, this paper accomplishes the optimal program based on the simple genetic algorithm
