摘要:

最小割问题(MCP)是图论中的经典NP(Nondeterministic Polynomial)-难问题,在图像分割和网络可靠性分析等方面具有广泛应用。警示传播(WP)算法作为基于因子图的推理方法,在求解组合优化问题时表现出较强的可扩展性与结构适应能力;然而,该算法在求解MCP时,它的传播路径选择、因子图构建和收敛性方面仍存在不足。为此,提出一种基于变量熵的警示传播(EWP)算法求解MCP。首先,通过引入基于隐马尔可夫模型(HMM)驱动的跳点机制选取核心传播区域;同时,利用批量映射的因子图转换方式有效压缩图结构的维度;最后,结合边缘概率与变量熵的冻结传播策略,引导信息传播过程更快地收敛。实验结果表明,EWP算法在多种图规模中表现出良好性能,尤其在大规模图优化问题中具有较大的应用潜力。

Abstract:

The Minimum Cut Problem (MCP) is a classic NP (Nondeterministic Polynomial) -hard problem with broad applications in image segmentation and network reliability analysis. Warning Propagation (WP) algorithm, a factor graph-based inference method, has shown good scalability and structural adaptability when solving combinatorial optimization problems. However, its effectiveness on MCP is limited by path selection, factor graph construction, and convergence. Therefore, an Entropy-based Warning Propagation (EWP) algorithm was proposed to solve MCP. First, a Hidden Markov Model (HMM) -driven jump-point mechanism was introduced to select core propagation regions. At the same time, a batch-mapping factor graph transformation way was employed to reduce graph structural dimensionality effectively. Finally, a propagation freezing strategy that combined marginal probability and variable entropy was adopted to accelerate convergence. Experimental results demonstrate that EWP achieves good performance on graphs with different sizes, and especially has significant potential in large-scale graph optimization problems.
