用于快速功能基序发现的约束多线性检测

Constrained multilinear detection for faster functional motif discovery

Ioannis Koutis

摘要:

图的主题问题是问一个给定的颜色的多重集是否出现在顶点着色图的连通子图上。这个问题的最快的已知参数化算法是基于对$k$ -多线性检测(k-MlD)问题的简化:检测作为电路呈现的多项式中的总次数k的多线性项。我们重新访问k-MLD和定义k-CMLD,它的约束版本,更忠实地反映图的主题。然后,我们给出了一个快速算法的k-CMLD。因此,我们得到更快的参数化算法的图形主题和它的变种。

英文摘要:

The GRAPH MOTIF problem asks whether a given multiset of colors appears on a connected subgraph of a vertex-colored graph. The fastest known parameterized algorithm for this problem is based on a reduction to the $k$-Multilinear Detection (k-MlD) problem: the detection of multilinear terms of total degree k in polynomials presented as circuits. We revisit k-MLD and define k-CMLD, a constrained version of it which reflects GRAPH MOTIF more faithfully. We then give a fast algorithm for k-CMLD. As a result we obtain faster parameterized algorithms for GRAPH MOTIF and variants of it.
