1.10.305. 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.
