Studies on controllability of directed networks with extremal optimization

Ding, Jin; Lu, Yong-Zai; Chu, Jian - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 24, pp. 6603-6615

Almost all natural, social and man-made-engineered systems can be represented by a complex network to describe their dynamic behaviors. To make a real-world complex network controllable with its desired topology, the study on network controllability has been one of the most critical and...

Optimizing partitions of percolating graphs

Boettcher, Stefan - In: Physica A: Statistical Mechanics and its Applications 266 (1999) 1, pp. 100-103

The partitioning of random graphs is investigated numerically using “simulated annealing” and “extremal optimization … “simulated annealing” is found to diverge in the thermodynamic limit. On the other hand, “extremal optimization”, a new general …
