To find an answer to the first question we need to examine the notion of “similarity” more closely. We define the similarity SN(A,B) of two program texts A en B under a minimum string length N as follows. Sup- pose we want to construct a copy of A by using segments of B only, restricting ourselves to segments of N essen- tial tokens or more. The more A and B are similar, the larger the part of A we can construct this way. SN(A,B) is then defined as the percentage of essential tokens in A that can be constructed this way.
