Minimum Common String Partition Parameterized by Partition Size is Fixed-Parameter Tractable

International audienceThe NP-hard Minimum Common String Partition problem asks whether two strings $x$ and $y$ can each be partitioned into at most $k$ substrings, called blocks, such that both partitions use exactly the same blocks in a different order. We present the first fixed-parameter algorithm for Minimum Common String Partition using only parameter $k$
