用块序自动机网络模拟并行布尔自动机网络的代价

On the cost of simulating a parallel Boolean automata network by a block-sequential one

Florian Bridoux, Pierre Guillon, Kévin Perrot, Sylvain Sené, Guillaume Theyssier

摘要:

在这篇文章中,我们研究的最小数量$κ$的额外的自动机,布尔自动机网络(BAN)与一个给定的块顺序更新计划,以模拟一个给定的BAN与并行更新计划需要。我们介绍了一个图,我们称之为$\mathsf{NECC}$图建立从BAN和更新计划。给出了$κ$与$\mathsf{NECC}$图的色数之间的关系。由于这个$\mathsf{NECC}$图,我们在$n/2$和$2n/3+2$($n$是模拟的BAN的大小)之间的最坏情况下绑定$κ$,我们推测这个数字等于$n/2$。我们证明了这个猜想:$\mathsf{NECC}$图的团数总是小于或等于$n/2$,并且对于双射BAN的子类,$κ$总是小于或等于$n/2+1$ .

英文摘要:

In this article we study the minimum number $κ$ of additional automata that a Boolean automata network (BAN) associated with a given block-sequential update schedule needs in order to simulate a given BAN with a parallel update schedule. We introduce a graph that we call $\mathsf{NECC}$ graph built from the BAN and the update schedule. We show the relation between $κ$ and the chromatic number of the $\mathsf{NECC}$ graph. Thanks to this $\mathsf{NECC}$ graph, we bound $κ$ in the worst case between $n/2$ and $2n/3+2$ ($n$ being the size of the BAN simulated) and we conjecture that this number equals $n/2$. We support this conjecture with two results: the clique number of a $\mathsf{NECC}$ graph is always less than or equal to $n/2$ and, for the subclass of bijective BANs, $κ$ is always less than or equal to $n/2+1$.
