摘要

由于算力请求具有特殊性和独特性，如何为一组异构算力请求寻找传输链路互不相交的有效路径集，使得该组请求能够到达各自目的算力节点，从而实现为该组请求分配算力资源，是当前算力网络面临的关键问题。首先，对异构算力请求的路由问题进行剖析，并通过建模将其转化为非确定性多项式（nondeterministic polynomial，NP）完全问题。针对该问题，提出一种优化型遗传算法。该算法从局部和全局两个层面进行设计：在局部层面，为保证快速收敛到目标解，采用单参数满足随机性策略初始化种群，使得种群广泛地分散在解空间中；采用多参数解（或路径）均衡选择策略进行选择操作，使得被选种群丰富多样；采用两层交叉策略进行交叉操作，目的是拓宽全域搜索广度；采用多参数随机单点变异策略进行变异操作，目的是深挖局域搜索能力。在全局层面，为保证路径不冲突，采用路径分发策略，通过构建求解矩阵，并借助评价函数、可行解随机选择、低需求优先避让原则等方法，确保最终找到一组可行解集。实验从异构算力请求的传输成功率、算法收敛延时比、算力网络负载均衡误差率等3个方面进行验证，相较于IGAGCT算法与RBDQN算法，该算法在传输成功率、算法收敛延时比和负载均衡方面分别平均优化了8.85%、15.51%、17.03%及10.41%、16.5%、16.81%。

Abstract

Due to the particularity and uniqueness of computing force requests

how to find an effective path set with non-intersecting transmission links for a group of heterogeneous computing force requests

so that the group of requests can reach their respective destination computing force nodes

and thus allocate computing force resources for the group of requests

is a key issue facing current computing first networks. Firstly

the routing problem of heterogeneous computing force requests was analyzed and was transformed into an nondeterministic polynomial (NP)-complete problem through modeling. An optimized genetic algorithm to address this issue was proposed. This algorithm was designed from both local and global perspectives: to ensure fast convergence to the target solution locally

a single parameter satisfying the randomness strategy was used to initialize the population

making it widely dispersed in the solution space; adopting a multi-parameter solution (or path) balanced selection strategy for selection operations

making the selected population rich and diverse; adopting a two-layer crossover strategy for crossover operations

with the aim of expanding the breadth of global search; adopting a multi parameter random single point mutation strategy for mutation operations

with the aim of deepening local search capabilities. To ensure that the paths did not conflict globally

a path distribution strategy was adopted. By constructing a solution matrix and utilizing evaluation functions

random selection of feasible solutions

and the principle of low demand priority avoidance

a set of feasible solution sets was ultimately found. The experiment verifies that algorithm has been optimized by an average of 8.85%

15.51%

and 17.03% in terms of transmission success rate

convergence delay ratio

and load balancing compared to the IGAGCT algorithm and RBDQN algorithm

and 10.41%

16.5%

and 16.81%

respectively from three aspects: heterogeneous request success rate

algorithms convergence delay rate

and load error rate of computing first networks.
