In the title text this is even taken into the bedroom, although it is a different ghost than the one preferred by the children. This is likely a subtle reference to euphemisms for sexual climax, such as "arrival", with delayed ejaculation generally preferred.
It should be noted that this app would be of no use for minimizing travel time. The user doesn't find out which route was fastest until after the first ghost has arrived. But as the current traffic situation will have changed by then, that route will not necessarily still be the fastest.
Racing Ghosts is a refference to Mario Kart ẞ qwertz (talk) 12:50, 21 September 2015 (UTC)
- This seems like a bit of a stretch to me. 18.104.22.168 13:35, 21 September 2015 (UTC)
- It's not a reference to Mario Kart specifically (lots of racing games have ghosts), but that's basically what this is doing - translating the concept of racing ghosts to the real world.--22.214.171.124 13:50, 21 September 2015 (UTC)
- Well, there are some fitness running apps that support a ghost runner mode, so you run against your best time and get updates if you are in front or behind of your „ghost“. Without actually being able to prove it, I believe (and always assumed) this idea is actually inspired from racing games like Mario Kart. 126.96.36.199 13:56, 21 September 2015 (UTC)

So in the title text, is he being replaced with the ghost who always *ahem* comes last? --SaturNine (talk) 12:53, 21 September 2015 (UTC)

Is this the first time Cueballs children were shown? ẞ qwertz (talk) 17:22, 21 September 2015 (UTC)
I don't know if it's worth mentioning that this appears to be a width-first (route-)search algorithm. A memory-heavy but guaranteed 'perfect' solver of best routing, at every point of choice (from the very first, how you start the journey), all possible/practical travel options are explored (including taking a journey in the 'wrong' direction, or waiting for the non-stop train that is not the first to arrive, to take advantage of connections with faster transport links), in parallel according to the total time (or other measure of efficiency) yet taken on each iteration. Unless any 'ghost' arrives at a node that has already been visited by a 'ghost', when it need not continue. Eventually, the most efficient son-of-a-son-of-a-son...-of-a-son-of-a-ghost will reach the destination, indicating the 'correct' answer. At least within the limits of the split-and-propogate algorithm, and the amount of parallelisation available to devote to the problem. (See also the multiple-overlayed 'searches' performed by two-minutes-of-Nicholas Cage, in the near-climactic scene in the film 'Next' (beware spoilers!).) 18.104.22.168 22:38, 21 September 2015 (UTC)
- Are you aware if such an app exists in real life? I'd be interested in trying to program one (albeit with less tangible ghosts). LowHangingFruit 14:19, 22 September 2015 (UTC)
- This is an extremely easy algorithm to program (I have taught it while teaching AP (high school) computer science), however it isn't an algorithm that will likely be useful to you since it has exponential time complexity. In other words, if there are more than a trivial number of possibilities to be examined, finding the solution through this algorithm would not finish before you were dead. For those of you who are about to say that if we could run a huge bunch of these possibilities in parallel: merging the results, memory management, context switching, and similar things, even if they could be done in constant time would still mean a constant amount of time for each of an exponential set of possibilities. 22.214.171.124 22:29, 22 September 2015 (UTC)tomb
- Can anyone give me a (couple) Wikipedia articles to read, so I can understand this comment? I'm really interested. 126.96.36.199 18:53, 23 September 2015 (UTC)
- Well, Breadth-first searching is probably your first step, then hit the appropriate sidebar for other methods. ('m a particular fan of the A* (A-Star) method, myself, but that's more probably due to my Dwarf Fortress addiction... ;) 188.8.131.52 14:29, 25 September 2015 (UTC)
Will his children have half-siblings that are fathered by the ghost that has replaced him in the bedroom? Or are ghosts infertile?184.108.40.206 04:07, 22 September 2015 (UTC)
Doesn't light do this according to some theory, sending out "investigation waves / photons" to determine the quickest way to get anywhere? I'm no expert on this, just some food for thought...
220.127.116.11 11:57, 22 September 2015 (UTC)
- Not really - or at least not real. There may be some "potential photons" in some attempts to describe some quantum-based theory ... but there will certainly be no investigation photons after wave collapse. -- Hkmaly (talk) 12:12, 22 September 2015 (UTC)
- Yes, really. He's doubtless talking about the Pilot Wave interpretation of quantum mechanics [] -- which is controversial but still mainstream, not crackpot gibberish; it was proposed/championed by the illustrious Boehm and Bell. Feynman and his advisor also worked on a similar theory. 18.104.22.168 23:41, 26 September 2015 (UTC)

If the simulations explore all travel possibilities, how long will it be until bike ghost gets run off the road by bus ghost? Or flattened by texting driver ghost? 126.96.36.199 12:30, 22 September 2015 (UTC)
- This reminds me of an Android (and probably iOS) game "Does Not Commute" which takes the classic 'ghost competitor' behaviour (note: 188.8.131.52, below, that it's a common thing) and makes them solid. You run (different) 'missions'/commutes across the playing arena with a succession of new vehicles, each time finding that all your previous commutes are happening, simultaneously, creating obstacles and hazards. You can collide with (or end up being run into by) another vehicle, replaying the path you set it upon in a previous round, and this causes you to rebound. (But there's no 'kickback' when contact is made with your prior 'self', which sticks solidly to its pre-played path. Thus no need to deal with contradictions and temporal paradoxes by deflecting a past-self thus potentially changing the entire arena (for good or bad) for every other attempt you made, trying to avoid everything else.) Worth a dabble, perhaps, but don't get addicted to it! 184.108.40.206 13:48, 22 September 2015 (UTC)
There's actually a very similar mechanism in the game Canvas Rider, where the best times on a track (it's a bike racing game with stick figures) can be clicked and a ghost that takes the same path with the same speed as those people appears and moves while you do. In fact, they actually look somewhat similar to the ghost in panel 4. 220.127.116.11 13:17, 22 September 2015 (UTC)
I strongly suspect this also references the concept of the Oracle machine as it relates to the NP hardness of the traveling salesman problem. TSP is in the complexity class NP Complete, and part of the most common proof that it is NP hard involves showing that it reduces to a polynomial time algorithm (and hence potentially practically computed) if there exists an oracle that can tell you if a route is optimal (the fastest) in constant time. I have never edited here before and don't know all the etiquette, so I leave it to a more experienced editor to consider this in the main article. The "ghost" would then be related to the Oracle because many real world "oracles" (as in fortune tellers or weird tripping priestesses of Apollo) claim to get answers by talking to ghosts. 18.104.22.168 22:17, 22 September 2015 (UTC) tomb
I'm also thinking there may be a worthwhile pun in there about the movie Ghost Dad, though I haven't found a suitable setup for that punchline. 22.214.171.124 21:50, 25 September 2015 (UTC)

I don't get how that one ghost has replaced him in the bedroom, since the ghost comes faster than he does! HE HE. 126.96.36.199 01:15, 5 February 2016 (UTC)
