This is a library and a command line tool for using the PSLQ integer relation algorithm.
It is used to find relations of the form
a[0]*x[0] + a[1]*x[1] + a[2]*x[2] + ... a[n]*x[n] = 0
where a[] are floating point big.Float values to a given precision
and x[] are integer big.Int values.
The algorithm will tell you that a relation exists, or not within certain bounds.
NB This requires Go >= 1.5 for big.Float support.
Install using go get
go get github.com/ncw/pslq/...
and this will install the library and build the pslq binary in
$GOPATH/bin.
See the go doc for details, in particular the example.
Usage pslq [Options]
Where file should contain decimal numbers, one per line. White space is ignored, as are comment lines starting with '#'.
If more than one file is passed in then they are concatenated
If file is '-' then stdin will be read
Options:
-iterations int
Number of iterations to use max (default 1000)
-prec uint
Precision to use (default 64)
-verbose
Print lots of stuff while running
