Weighted automata with discounting

Abstract: Abstract:We investigate weighted automata with discounting and their behaviours over semirings and finitely generated graded monoids. We characterize the discounted behaviours of weighted automata precisely as rational formal power series with a discounted form of the Cauchy product. This extends a classical result of Kleene-Schützenberger. Here we show that the very special case of Schützenberger's result for free monoids over singleton alphabets suffices to deduce our generalization.

“…Finally, we consider algebraic weight structures with addition operation and a collection of multiplications, which could realize, for instance, the average operations in quantitative automata. They also model discounting operations in weighted automata investigated earlier [10,8,20,12]. Using our previous results, we obtain a Kleene characterization of automata over such weight structures, which extends Schützenberger's original result.…”

“…Recently, for a theory of systems engineering, it was investigated in [11]. For weighted automata, it was introduced in [15], and the discounting behaviors of weighted Büchi automata were characterized as the ω-rational formal power series; this was further investigated in [18,23,35]. As semirings, here we consider the max-plus and the min-plus semiring which are fundamental in max-plus algebra [10,27] and optimization problems [52].…”

“…As our main contributions, we will (1) extend the weighted logic of [12] to weighted automata with discounting for finite words and arbitrary commutative semirings as investigated in [15,18,23,35]; our present form of discounting is slightly more general (cf. Theorem 11(a)); (2) provide for the max-plus and min-plus semirings of real numbers a weighted logic with discounting which is expressively equivalent to the weighted Büchi automata on infinite words of [15] (cf.…”
