Balanced decomposition of a vertex-colored graph
Discrete Applied Mathematics, 2008 AbstractA balanced vertex-coloring of a graph G is a function c from V(G) to {−1,0,1} such that ∑{c(v):v∈V(G)}=0. A subset U of V(G) is called a balanced set if U induces a connected subgraph and ∑{c(v):v∈U}=0. A decomposition V(G)=V1∪⋯∪Vr is called a balanced decomposition if Vi is a balanced set for 1≤i≤r.In this paper, the balanced decomposition ...

Proper Magic Sigma Coloring of Specific Graphs [PDF]
Computer Science Journal of MoldovaA coloring $\varphi: V(G)\rightarrow \{1,2,\ldots,k \}$ is called a magic sigma coloring of $G$ if the sum of colors of all the vertices in the neighborhood of each vertex of $G$ is the same.

Recent Advances in Graph Vertex Coloring [PDF]
, 2013 Graph vertex coloring is one of the most studied NP-hard combinatorial optimization problems. Given the hardness of the problem, various heuristic algorithms have been proposed for practical graph coloring, based on local search, population-based approaches and hybrid methods.

Advanced Healthcare Materials, EarlyView.This study introduces a wireless and miniaturized concentric‐electrode tDCS (CE‐tDCS) system tailored for freely moving mice. The device enables focal and multi‐site cortical stimulation via a lightweight, Bluetooth‐controlled platform. By integrating local neuromodulation with real‐time behavioral analysis, the system provides a robust tool for ...
