Problem in Viterbi algorithm

[mrluin]

Hi,

Thanks for your works!
But I have some question about Viterbi Algorithm in decoding_formulas.py

I think the shape of self.network_space is [layers, scales, choices], that is layers, samples, and rates in the for loops, right?
If so, should be code in line 50 is

if (sample == 0 and  rate == 0) or (sample == 3 and rate == 2):
    continue

because the corresponding choices of rate 0, 1, 2 are ↗, →, and ↘.
If I am wrong, could you give me some hints and further explanations?
Thanks in advance.

Best regards,
TTB

Yes, you are right. Thanks very much ! :)

Sorry, I din't check the code before and make a mistake
sample == 3 rate == 0 denotes the information flow will come from the sample==4 in previous layer, it is wrong, and same as sample == 0 rate == 0
So it shold be

if (sample == 0 and  rate == 2) or (sample == 3 and rate == 0):
    continue

Thanks ：）
