Algorithms for some intersection graphs,Several intersection graphs such as curves-in-the-plane graphs, circular-arc graphs, chordal graphs and interval graphs are reviewed, especially on their recognition algorithms. In this connection graph realization problem is mentioned.

The two disjoint path problem and wire routing design,A new polynomial time algorithm is presented for finding two vertex-disjoint paths between two specified pairs of vertices on an undirected graph. An application of the two disjoint path algorithm to the automatic wire routing is also discussed.

In this paper, in connection with the critical sets of the edge set of a graph, some new theorems on central trees of the graph are presented. Also, a few examples are included to illustrate the applications of these theorems.

On the layering problem of multilayer PWB wiring, the special case of street capacities up to two in each layer, and it is reduced to a problem of the interval graph by relaxing some restrictions in the original problem. Then, a heuristic algorithm is proposed for this problem.
