The Steiner tree problem is defined as follows-given a graph G = (V , E) and a subset X ⊂ V of terminals, compute a minimum cost tree that includes all nodes in X. Furthermore, it is reasonable to assume that the edge costs form a metric. This problem is NP-hard and has been the study of many heuris

The crisscross space is rectangularly structured. Start from a Cartesian coordinate system with distance D of points defined as D(P1, P,)=Ixz-x,I+Jy2-y,I, where P,=(xr,y,) and P,(x,, yz) are points in the real plane. The general Steiner problem is to find the minimum point P of @(P)=~~=l ciD (P,, p
