It is used to save storage in implementations of functional programming languages, as well as in symbolic manipulation and computer algebra systems. In compiling, the compaction problem is known as the “common subexpression problem” and it

Two-way automata with multiplicity,m to this more general case. We in fact show that it holds in the case of automata with multiplicity in a commutative semiring, provided that an additional condition is satisfied. We prove that this condition is also necessary in a particular case. An application is given to zig-zag codes using special two-way automata.
