Thanks for your response! and thanks for your work with the software, as well :) Although I also thought of the commercial reasons, and I personally believe that sm2 is enough to learn stuff by itself, what I've seen that "worries" me a little is the difference in workload. Particularly about this part in the algorithms's comparison article: "Feb 22, 2018: We have finally added a simulation of Algorithm SM-2 to SuperMemo for Windows and have come up with the average least squares metric of 53.5685% (for Algorithm SM-2). For comparison, Algorithm SM-17 results in 37.1202% (a million repetitions dataset). This may not sound impressive, however, for shorter intervals, the load of repetitions might easily be 2-10x greater assuming no delays (i.e. executing repetitions as prescribed). Back in 1989, we could see that even Algorithm SM-5 would reduce repetition loads twice as fast as SM-2. For comparison, Algorithm SM-17 rarely goes 5pp above Algorithm SM-15 in R-Metric measure, and even small gains have a significant impact on workload (esp. at shorter intervals)." link http://supermemopedia.com/index.php?title=SuperMemo_or_Anki What do you think? -- You received this message because you are subscribed to the Google Groups "mnemosyne-proj-users" group.
