Abstract(in English) The k-layer constrained via minimization problem (kCVM) is to find assignment of wire segments to k layers so that the number of vias is minimum, and is NP-hard even if k≧3. So, heuristic algorithms for kCVM are proposed, and it is known that K-LAG has the highest capability among those algorithms. The subject of this paper is to propose two heuristic algorithms K-LAG-V and K-LAG-VL that are enhanced versions of K-LAG. Based on experimental results, it is shown that proposed algorithms are useful for solving kCVM with k=4, 6, 8, 10 or 12.
