A new algorithm for the group minimization problem (GP) is proposed. The algorithm can be broadly described as follows …-known algorithm of Glover, and checked for non-negativity. The first non-negative point is an optimal solution of (GP). Advantages and … disadvantages of the algorithm are discussed; in particular, the implementation of the algorithm (which can be easily extended so as …

Focusing on a multi sector economy linked through a supply network, we show how structural properties of … the supply network determine both whether aggregate volatility disappears as the number of sectors increases (i … aggregate output from its mean) to sector-specific volatility and to the structural properties of the supply network …
