NAME

       pyecm - Number factorization with the Elliptic Curve Method

SYNOPSIS

       pyecm [OPTIONS] [FACTORS]...

DESCRIPTION

       pyecm  factors numbers using the Elliptic Curve Method (ECM). If FACTORS is given, it will
       factor each one of these. Otherwise, it will factor from  standard  input.  You  can  type
       "exit" to quit pyecm at any time.

       -h, --help
              Get help using pyecm.

       --portion=num
              Does  only  part  of  the work for factoring, corresponding to what fraction of the
              total work the machine is doing. Useful for working in parallel.  For  example,  if
              there are three machines: 1GHz, 1GHz, and 2GHz, print should be set to 0.25 for the
              1GHz machines and 0.5 for the 2GHz machine. Implies -r and  -v.  -r  is  needed  to
              avoid duplicating work and -v is needed to report results.

       --ov=num
              Sets the value of the internal parameter ov, which determines the trade-off between
              memory and time usage. Do not touch if you do not know what you are  doing.  Please
              read  all  the  documentation and understand the full implications of the parameter
              before using this switch.

       -n, --noverbose
              Terse. On by default. Needed to cancel  the  -v  from  the  --portion  or  --random
              switches. If both -n and -v are specified, the one specified last takes precedence.

       -r, --random
              Chooses random values for sigma, an internal parameter in the calculation.  Implies
              -v; if you're doing something random, you want to know what's happening.

       -v, --verbose
              Explains what is being done with intermediate calculations and results.

EXAMPLES

       pyecm 2^3-1 1000 "(3^13+2)*5"
              Factor 7, 1000, then 7971625.

       pyecm  Get factors from standard input.
