According to your computations, after ten days the cities are contaminated ABOVE 100%. You noticed it, and you hid it with well placed if statements. But the main problem is that you are counting many infection events more than once. As an example, on day 2 the correct values should be (using your format): A = 10000, B = 1900, C = 1981, D = 1981, E = 199.

Day 0 infection B: 0 Day 1 infection B: 1000 (10000 * 0.1) Day 2 infection B: 2000 (1000(day 1) + 10000 * 0.1 = 2000) Where did your 1900 come from for city B. Please answer with calculations. Last fiddled with by Kebbaj on 20200413 at 08:49

1000+9000*0.1= 1900. Otherwise, some people infected on previous days are counted over and over again, quickly exceeding 100%.

Yes your reason is better than mine. I had seen that the source city A with a high viral load of 10000 infected cases can count 1000 healthy cases in city B.

Are there many equivalent adjacency matrices with 70,0074873 % after 10 days or is my code wrong?

Not sure, but there must be many equivalent matrices, at least the permutations of all the rest of the points except the originating city, minus the degenerate cases due to isomorphic connections. If the graph is dense, there will be many degenerate cases, but if the it is sparse, you will have little number of degenerate cases.

The optimum result of 70.007... for 10 days and 8 nodes corresponds to only one unlabeled connected graph. There are several ways to chose the root node in this graph all leading to the same probability of "all nodes infected". Since the updated description says
