There are 2 methods for minimization in AMBER; steepest descent and
conjugate gradient. It is best to use both methods in minimization because
steepest descent will quickly move the system to the local minimum
and conjugate gradient will minimize the system around the local minimum
area.
The idea of minimization is to get rid of bad contacts. If your system is
fine after minimization (whether you used conjugate gradient and/or
steepest descent), then you can do the production runs to this minimized
structure.
Best,
