My mistake. I updated the file and forgot to include the 'import 
algorithm' directive. The file is now fixed to include it. 
Download the corrected version or patch your file accordingly.

As stated in the file intro **YOU MUST DO THIS** to get it to 
compile with current Nim (they were supposed to fix this in this 
version 0.19.0 but didn't).

  To compile for nim versions <= 0.19.0 do following:
  1) in file: ~/nim-0.19.0/compiler/vmdef.nim
  2) set variable: MaxLoopIterations* = 1_000_000_000 (1 Billion 
or >)
  3) then rebuild sysem: ./koch boot -d:release

If you are using 'choosenim' to install Nim (highly advisable) 
the full path is:

  ~/.choosenim/toolchains/nim-0.19.0/compiler/vmdef.nim

I'll post performance results from my laptop to give reference 
times to compare against.
