wow, that's way off! for n = 2, n^n^n^n returns 65536. for n = 3, javascript thinks its infinity. i guess BOAT should start using decimal values for n so we can detect this problem.

Yes, this is likely true - I really need to think about it more, though. I don't know how to do static or runtime analysis, so I can't say much about it

Yes, it analyzes a formula or recurrence relation - sorry to get your hopes up :-D I wish it could analyze source code, but the halting problem says that would be a bit difficult. I think one could execute source code with varying size inpu

Thanks for the feedback and good catch! The list of big O classes is the following: var classes = [ define_func("0"), define_func("1"), define_func("lg(n)"), define_func("sqrt(

BOAT is a quick tool I made for analyzing and comparing the Big O growth rate of mathematical functions. I built it to help students get a sense of Big O notation, as its a common class exercise to have to rank several math functions in ter

good point! i'm not against a DSL. as I was working on plait.py, one thought going through my head was: "am i re-writing haskell or lisp but worse"? my experience with python and DSL is that I need to use YACC / PLY to c

it's a drop in replacement for stympy/faker, but not joke2k faker joke2k/faker is python and the data is stored in code (all or most of the random values are in .py files around the codebase), perhaps leading to its slowness.

part of what prompted the work on plait.py was that joke2k/faker was reasonably slow to generate 10K fake names for me: https://paste.ubuntu.com/26354987/ PS. that's a really cool python tip!

if you already have a way of printing XML, you can add a "printer" field (that is a python function) to your template, like so: http://github.com/plaitpy/plaitpy/blob/master/templates/test..

if you create a template and keep calling .gen_record(), i think it will do what you want. Template() does not implement python's __next__ or __iter__ at the moment, but that's a good idea - i'm very open to diffs :-D
