The multicanonical work has been reviewed but there's some ambiguity as to what the best implementation is. It's in a fully working state for DynamO 1.4 as of this commit...

@jonyrock's solution is by far the best for me. I'm getting heap issues trying to run npm build on a Raspberry Pi 4 1Gb. As I can't increase my available...

Hey, thanks for reporting this! I'll add it as a test case and figure out what's going wrong. Be right back!

I think I've fixed this in the latest commit ca9583c71116844d6dbd995ee931fefc248ea74b. I was incorrectly calculating upper bounds on the real roots using the zero coefficients. This should be fixed now. Note,...

Cool application and thanks for the papers! This was something I dived into far too much a while ago and I hadn't seen these. You have summarized the problem correctly,...

Thanks again for more detective work. So your two examples are (just thinking out loud here) 14482.000000000001818989403545856-83591.999999999985448084771633148*x+84887.999999999970896169543266296*x*x+x*x*x*1.3022974889306702395208061776649e-11+x*x*x*x*8.0779356694631608874161005084957e-28 Which is this on wolfram alpha, showing two real roots: https://www.wolframalpha.com/input?i2d=true&i=14482.000000000001818989403545856-83591.999999999985448084771633148*x%2B84887.999999999970896169543266296*x*x%2Bx*x*x*1.3022974889306702395208061776649e-11%2Bx*x*x*x*8.0779356694631608874161005084957e-28 And 35842-x*57720+x*x*59799.999999999985448084771633148-x*x*x*5.2252677024996035907674102414044e-12+x*x*x*x*2.0194839173657902218540251271239e-28...

OK I've confirmed this is an issue with the Sturm construction/solution. The bounds are correctly calculated. This might be hard to solve, there's lots of places that precision can be...

Notes for later. One issue with this is the loss of precision in polynomial evaluation. This paper has some excellent ideas around improving precision: https://arxiv.org/ftp/arxiv/papers/0805/0805.3194.pdf Need to implement this along...

More notes while I work on this: An examination on how roots depend on the coefficients, just general background reading on polynomial precision https://www.skewray.com/articles/how-do-the-roots-of-a-polynomial-depend-on-the-coefficients Glad to hear you're making progress...

Thank you guys! this is something I've been playing with for months trying to get working. To help others, here's a docker file that takes the overleaf CE, installs common...
