Good morning Zmn!
That is indeed precisely what we do. We usually quantize the min-cost flow
into minimum shares of, say, 10kSat to 100kSat. This makes the algorithm
run faster and loses very little precision. It also gives a simple way of
dealing with (reasonable) min-htlc-size values.
Cheers,
Stefan
