(Asahi Shimbun)   Japanese graph theorists unhappy that local baseball leagues reject their road-trip scheduling algorithms. "I hear Nippon Professional Baseball (NPB) spends six weeks scheduling the trips. Our software could do that in the matter of 30 seconds"   (ajw.asahi.com) divider line 14

Good luck changing the way anything is done in Japan.

Stadium availability, plus the teams know which opponents draw and which don't. There's more factors in scheduling than distance.

As someone that turns transactional data into predictive models as a job, I can sympathize. There are some people that, even after you've proven your algorithms work in over 95% of cases, still think they know better even though their predictions are no better than pure chance.

TV presence and politics as well.  These guys may be good at math, but they obviously have absolutely no idea what they're dealing with.  The definition of a "perfect" schedule is one that makes the fickle boss happy.

And yet, those factors could be easily implemented into their algorithm and it would still take 30 seconds to run the program.

And above all that, matchups. When you play the good teams, when you play the bad teams, teams love having some control over that.

It's funny how people lament unemployment and then wonder why people aren't excited about their idea to eliminate more jobs.

Like I'm gonna let some bean counting graph nerds dictate when my baseball swatting nipponese supermen are going to travel. My son in law does that.

I'm not surprised the Central League turned them down. The six teams in that league are fairly bunched together on Japan's biggest island. I doubt that travel distance carries any significant weight in scheduling, compared to when you get to host the Giants (the Yankees of the NPB), for example.

The Pacific League might be more interested in what they have to offer, since they're a lot more spread out across Japan.

Yeah, like that stupid cotton gin or that factory thing they keep talking about.

I don't think that helping schedule a professional baseball team is really going to lead to a huge expansion of jobs in other industries or revolutionize the world.

Also, Japan is tiny.  I'm sure travel is much less of an issue as compared to MLB in the US.

Yeh its not hard so the schedule is like that becuase people want it like that. Its not like English football with four profesional leagues where teams close to each other can't play at home at the same time, a couple of teams ground share, rival fans can't travel in the same direction on public transport and other international sporting events. For example Middlesbrough can't play at home the same time as Sunderland play at home even though they are in different leagues and Arsenal can't play in Manchester the same time that Spurs play in Liverpool as both are on the same transport routes.

/Even that isn't that hard

Linear programming has been around for 70 odd years yet nobody has any idea what it is or what it's capable of accomplishing.
"Yeah but can account for this?"
Yes. Yes it can.
