Weighted finite automata (WFA) are used with accelerating hardware to scan large genomic banks. Hardwiring such automata raise surface area and clock frequency constraints, requiring efficient ε-transitions-removal techniques. In this paper, we present new bounds on the number of new transitions for several ε-transitions-removal problems. We study the case of acyclic WFA. We introduce a new problem, the partial removal of ε-transitions while accepting short chains of ε-transitions.
