融合Gromov-Wasserstein求解器的比较
该示例说明了使用4种不同求解器计算属性图的FGW，基于条件梯度[24]、Sinkhorn投影[12, 51]和交替Bregman投影[63, 64]来估计距离。
我们生成两个图，遵循随机块模型，并赋予节点特征，并计算它们的FGW匹配。

融合的Gromov-Wasserstein匹配的可视化
我们给右侧的图中的节点上色 - 然后根据FGW匹配的最佳运输计划投影其节点颜色。我们根据发送的质量调整跨域链接的强度，如果发送的质量不为零，则添加最小强度0.1。对于每个匹配，所有节点的大小与其从OT计划的边际计算得到的质量成比例，以说明潜在的可行性错误。注意：颜色指的是簇 - 而不是节点特征
