Table S. 1 presents the statistics <strong>of</strong> the five test problems. The Linking rows and columns<br />
are those constraints and variables which have nonzero enaies in the matrices L, when the<br />
original problerns are decomposed into four parts. The parenthesis in "Linking Cols (or "Linking<br />
Rows") shows the ratio <strong>of</strong> the number <strong>of</strong> linking columns (or rows) to the number <strong>of</strong> columns<br />
(or rows).<br />

The linking variables in TEP are 'LFLOWS (R.RR.T)' representing the arnount <strong>of</strong><br />
electricity that flows from region R to region RR at time T, and the Iinking consaaints are the<br />
elecuicity demand consuaints in each region R at time T, 'LTRADE(R,T)'. NAEP has 7 regions<br />
<strong>of</strong> Westem Canada (WC), Eastern Canada (EC), Westem US. 0, Northern U.S. (NU),<br />
Eastern U.S. (EU). Southem U.S. (SU) and the Rest <strong>of</strong> the World (RW). The 7 regions were<br />
muped into 4 pans: WC, EC and RW. WU and NU, and EU and SU. The linking variables and<br />
C<br />
consmints <strong>of</strong> NAEP are those representing energy flows arnong the 4 parts. HEPGl is fomiulated<br />
using rime index and scenario index as shown in Figure 5.5, so it cm be divided into the
