I just made a Genetic Algorithms calculator you can try at http://www.gregthatcher.com/Stocks/GeneticAlgorithmCalculator.aspx I'm not a "quant expert" like all of you (I'm just a programmer), but here is what I've found. 1.) If you set the constraints up correctly, the results are amazing. e.g. you can get portfolios that have very high return and low ...

Theoretically speaking: Haskell is elegant and has many of the theoretical advantages (language ...

You may have a look at a list of clustering algos available in sklearn here, but I think all of them are of $O(n^2$) complexity. As well, have a look at the TSNE clustering algo, which is supposed to be $O(log(n)*n)$, but this may not be the fact depending on a particular implementation. A particular case in point is again Python sklearn implementation of ...

One idea is Dynamic time warping (DTW). There is an R package for that: dtw Here is the vignette:Computing and Visualizing Dynamic Time Warping Alignments in R: The dtw Packageby Toni Giorgino And here is an example from Systematic Investor with full code: Time Series Matching with Dynamic Time Warping
