Given an arbitrary graph G=(V,E) and a proper interval graph H=(V,F) with E@?F we say that H is a proper interval completion of G. The graph H is called a minimal proper interval completion of G if, for any sandwich graph H^'=(V,F^') with E@?F^'@?F, H^' is not a proper interval graph. In this paper we give a O(n+m) time algorithm computing a minimal proper interval completion of an arbitrary graph. The output is a proper interval model of the completion.
