New in pyecm 2.0 (Sep 25, 2008)
- Made asymptotic improvements at the expense of a constant factor. It should now be faster for numbers greater than 30 or so digits but slower for numbers less than that.
- Added ability to type expressions instead of plain numbers. For example, the program will now factor "2^30-1" instead of making you type "1073741823".
- Added capability to run pyecm in parallel.
- Added command line switches, such as a verbose mode and an ability to select sigma (an internal parameter) randomly.
- Improved compatibility with installations lacking gmpy and/or psyco.
