Madars Virza abf63ed568 Document mixed addition optimization. 2015-04-27 10:03:34 +03:00
Madars Virza 94d1b48032 Add more debugging printouts for gadget_from_r1cs 2015-04-27 10:03:34 +03:00
Madars Virza 446eb80296 Specify license for the TBCS to USCS reduction script. 2015-04-27 10:03:33 +03:00
Madars Virza 859905fc64 operator+ for linear_combination is a linear time operation, so 
building a O(n)-sized linear combination by repeatedly concatenating
O(1)-sized linear combinations is O(n^2) operation. (This is akin to
the caveat for Python strings.)

This commit optimizes the constructions of CRH and packing gadgets to
be quasi-linear time operations, down from previously quadratic time.
