Altera Quartus II Settings File - Manual (Page 727)

ROUTER_EFFORT_MULTIPLIER
Controls how quickly the router tries to find a valid solution. The default value is 1.0 and legal values must
be greater than or equal to 0.25. Values higher than 1.0 may improve routing quality at the expense of
run-time on difficult-to-route circuits. Values lower than 1.0 can reduce router run-time, but usually
reduces routing quality slightly.
