Abstract We simulate the dynamics of a muitineuron model (RS model) witli an energy
function given by tile product between the squared distances in phase space between the state of
tile net and the stored pattems. We obtain the relative frequency f(m~) that an arbitrary pattem
is retrieved from an initial overlap m~ and estimate the size of the basins of attraction for different
activities a. Two limit cases are taken into account : when pattems and antipattems are stored
(p.a.s.) and when only the pattems are stored (o.p.s.). For the a =
0.5, p.a.s. nets a limit for the
load parameter was not found, but for the other cases (a,0.5 or o.p.s. configuration) the
relative size of the basins of attraction may become too small.
