We introduce and study the doubly balanced connected graph partitioning problem: LetG=(V,E) be a connected graph with a weight (supply/demand) functionp:V→ {−1, +1} satisfyingp(V)=∑j&isinVp(j) = 0. The objective is to partitionGinto (V1,V2) such thatG[V1] andG[V2] are connected, ∣p(V1)∣,∣p(V2)∣≤cp, and max{ ∣V1/V2∣,∣V2/V1∣} ≤cs, for some constantscpandcs. WhenGis 2-connected, we show that a solution withcp=1 andcs=2 always exists and can be found in randomized polynomial time. Moreover, whenGis 3-connected, we show that there is always a “perfect” solution (a partition withp(V1)=p(V2)=0 and ∣V1∣=∣V2∣, if ∣V∣≡ 0 (mod 4)), and it can be found in randomized polynomial time. Our techniques can be extended, with similar results, to the case in which the weights are arbitrary (not necessarily ±1), and to the case thatp(V)≠ 0 and the excess supply/demand should be split evenly. They also apply to the problem of partitioning a graph with two types of nodes into two large connected subgraphs that preserve approximately the proportion of the two types.
