  In this paper we present a method to study the folding structure of a simple
model consisting of two kinds of monomers, hydrophobic and hydrophilic. This
method has three main steps: an efficient simulation method to bring an open
sequence of homopolymer to a folded state, the application of a painting method
called (regular hull) to the folded globule and the refolding process of the
obtained copolymer sequence. This study allows us to suggest a theoretical
function of disorder distribution for copolymer sequences that give rise to a
compacted and well micro-phase separated globule.
