What is the best way of getting around "inner London" (United Kingdom)? Is it taxi, personal automobile, Tube (subway) -- or even bicycle (ha ha ha)?
Did you decide yet? So did you measure "best" by convenience, cost, health benefits, or speed? Or did you construct a carefully weighted measure of all of those, such as being willing to trade 1 minute longer travel time for each 2000 Calories of fat burned? Or should it be 1.5 minutes and 1000 Calories? What scientific study did you use to decide the trade-offs?
Oh, by the way: multiple tests have shown that during a typical work-day afternoon, the lowest cost way of getting around inner London is by bicycle, but the healthiest way of getting around inner London is instead by bicycle; and on the third hand, the fastest way of getting around inner London is... by bicycle.
So when you are selecting an ANN, what do you mean by "best" ?
