Rows represent organisms, the order of which is kept constant in the comparison. So for example in the first row, organism 1 has the gene "a" and the gene "b", in the second row organism 2 don't have the genes "a" and "b", in the tirth row organism 3 has the gene "a" but not the gene "b" and so...

I will try to explain my problem better. I am carrying out research in genomics by analysing the logical relationships of genes in different genomes (i.e. organisms). In the following table columns represent two genes (“a”, “b”); rows represent genomes; “1” indicates that the gene is present...

In fact all the relations are of the form "a(k) & b(k) = x_k", where x is either true or false. An example using the logical connector AND would be AND a b 1 1=T 0 0=F 1 0=F 1 1=T 0 1=F Here the number of different permutations of "a" is 5!/(3!2!) and the number of...

After much thinking I am trying to get a help from the board. Sorry for being naïve and thank you in advance for your answers. Suppose you have to arrays made up of zeros and ones a=(1,1,0,1,0,0) b=(1,0,0,1,1,0) and a logic relationship to compare the elements of the two arrays in a...
