查询词典 integer optimization

Although departed methods such as dynamic programming, integer programming, and branch bound method can solve small scale problems, the rise in execution time of these methods is exponential with the number of generating units.

虽然在以往的研究中，已有许多方法使用在此问题上，例如动态规划法、整数规划法及支界法等，但是由於这些方法所需的求解时间会随机组数的增加呈指数关系成长，因此都比较适合於小规模系统上使用。

When problem scale is small, we can adopt many classical algorithms such as linear programming integer programming, branch and bound method to solve this problem.

当问题规模较小时，可用线性规划、整数规划、动态规划等经典算法求解。

Second, according to model characteristic, such as non-linear, non-convex, multiple-peaked and so on, the paper discusses limitation of traditional solving algorithm, such as branch and bound method, GBD method and OA method, puts forward penalty function-makeup integer algorithm and genetic algorithm, analyses procedures of genetic algorithm, such as selection, crossover and mutation, brings forward modifications for specific realized problems of genetic algorithm, such as selection of initial points, operator design, adoptive value adjustment, constraint treatment and so on, and works out correlated solving program.

其次针对该模型非线性、非凸、多峰等特点，讨论了分支定界法、GBD法和OA法等传统求解算法的局限性，提出了罚函数一凑整算法和遗传算法的求解思路，对遗传算法的选择、交叉、变异等过程进行分析，对遗传算法初始点选择、算子设计、适应值调整和约束处理等具体实现问题提出了改进措施，并编制了相关的求解程序。

Using some metrics as integer, a good path which guarantees delay, delay jitter and buffer can be found in polynomial time complexity.

The characteristic of fractional order differential equation iscontaining the non-integer order derivative. It can effectively describe the memory andtransmissibility of many kinds of material, and plays an increasingly important role inengineering, physics, finance, hydrology and other fields.

分数阶微分方程的特点是含有非整数阶导数，能非常有效的描述各种各样的物质的记忆和遗传性质，在工程，物理，金融，水文等领域发挥越来越重要的作用。

The results showed that the statistical characteristics and changing regularity of the integer multiple spiking from the experiment were similar to those from the stochastic Chay model, but different obviously to those from the deterministic Wang model.

结果发现，实验和随机模型经随机自共振产生的整数倍峰放电节律具有相同的统计性质(峰峰间期越大，出现的频度越低，约呈指数递减)和变化规律，与确定性Wang模型产生的整数倍节律明显不同。

The results show that the period-adding bifurcation obeys the deterministic mechanism decribed by Chay model and lightly affected by stochastic factors. In the corresponding parameter region, the integer multiple spiking generates only when the stochastic factors are introduced to the model. The phenomenon is autonomous stochastic resonance.

从模拟实验结果的角度看，加周期分叉过程遵从Chay模型决定的确定性机制，随机因素对其有影响但影响较小；而在相应的参数区间，整数倍节律则是在随机因素驱动下产生，是随机共振现象，是由确定性机制和随机因素共同作用的结果。

According to Sarkovskii's theorem, if the continuous self-map f of the closed interval has a 3-periodic orbit, then f must has an n-periodic orbit for any positive integer n But f can not has all n-periodic orbits for some n.

但f不可能有所有类型的n-周期轨。例如：则f仅有两种类型的3-周期轨中的一类。这表明Sarkovskii定理远远没有给出周期轨之间的关系的全部信息。

This allows // the function to accept both integer and floating-point values // without coercing either type.
