Awesome Miner gets all coin information, including which algorithm it's based on, via the coin statitics providers like WhatToMine.com and CoinCalculators.io. In case a coin changes the algorithm, it may take some time before these providers changes the algorithm. Awesome Miner can override the algorithm for a coin via the Options dialog, Statistics section, where the setting Override coin algorithm can be used to specify that a specific coin should be using another algorithm.
