Let say,I have a conjugated cyclic polygon and its nodes are given
by the list: list_p=[a,b,c,d,e,f,g,a,a,b,d,d,d,d,d,c,c,e,e,a,d,d,g]. If X
are any elements in a list_p except d, and Z is also an element of
list_p but has
value only d, i.e, Z=d. Now,I want to compute the number of paths with
Y consecutive nodes, example: a-d-d-e,a-d-d-a, a-d-d-d-g, etc.
Consecutive path length
of Z can be 1,2,3,4 or 5.
To generalize: Find total number of paths with consecutive X-Z-Y
sequence for path length of
z within range(1,6): or
(i) X-Z-Y for len(Z)=1
(ii) X-Z-Y for len(Z)=2
(iii)X-Z-Y for len(Z)=3
(iv) X-Z-Y for len(Z)=4
(v) X-Z-Y for len(Z)=5
Is there any easy way to program this using python networkx or
igraph? , can numpy group have some module to simplify this problem?
