5. Nets and coalitions 3. Coalition Formation<br />

We consider 3 search algorithms:<br />

MERGE: Breadth-first search from the top.<br />

SPLIT: Breadth first from the bottom.<br />

Coalition-Structure-Search (CSS1): First the<br />

bottom 2 levels are searched, then a<br />

breadth-first search from the top.<br />

MERGE might not even get a bound, without looking at<br />

all coalitions.<br />

SPLIT gets a good bound (k = |A|) after searching the<br />

bottom 2 levels (see below). But then it can get slow.<br />

CSS1 combines the good features of MERGE and SPLIT.
