The implementation seems a very lot slower than the python one on a use case from wookenny. See #1
auto matcher = difflib::MakeSequenceMatcher<>(a, b);
for(uint i=0; i<1000; ++i){
matcher.set_seq1(a);
ratio = matcher.ratio();
}
std::cout<< ratio <<std::endl;
for i in range(1,1001):
s = difflib.SequenceMatcher()
"""had to do call set_seqs with swapped argument each time
otherwise the computation is much faster due to prev. stored computations"""
if(i%2==0):
s.set_seqs(a,b)
else:
s.set_seqs(b,a)
r = s.ratio()
print r
The python version, on long sequences, find less matches, or no matches at all, where the C++ one still find them, at a huge execution cost. Must find out why.
