minimize powell <minimize-powell-statement> end
<minimize-powell-statement> :==
drop=<real>
Expected initial drop in total energy. Default=0.001
tolgradient=<real>
Tolerence for early termination of minimization. If the norm
of the gradient of the total energy falls below this value
minimization will stop. Default=0.0001
debug=<logical>
Write verbose messages during minimization. Default=false
