If you are looking for the most efficient algorithm, then I can say with good confidence that nobody has it figured out yet. The biggest problem with SM is that it is designed for declarative knowledge. I consider it revolutionary in this area, but nevertheless, focusing entirely on declarative knowledge isn't the best strategy either. I'm not so sure about plasticity -- what kind of plasticity is this? How would you test it? Synaptogenesis is out of the question (because this is not a cellular-scale operation). Standardized tests? That itself is full of confounds. I have come across some studies regarding memory decay. Perhaps some algorithm is involved. If you dig around I'm sure you can find something, but conclusive data about the effectiveness of various aglos... you'd think that if it exists, the whole world would know by now.
