People have been <a href=\"http:\/\/nypost.com\/2016\/07\/09\/pokemon-go-is-afflicting-players-with-real-world-injuries\/\">walking into traffic, trees and parked cars<\/a> at an alarming rate while they compete to catch little animated beasties that are sort-of kind-of actually walking down the street next to us. I&#8217;m talking about <a href=\"http:\/\/www.vox.com\/2016\/7\/12\/12158372\/pokemon-go-ios-android-game-questions\">Pok&eacute;mon Go<\/a>.  The new augmented reality game that has you <em>catching &#8217;em all<\/em>, all over the place.  <\/p>\n<p>The original Pok&eacute;mon was a two player video game, which I am afraid to admit, I never actually played.  Nevertheless, I was curious about the nature of the game: what sort of Pok&eacute;mon strategies are there?  And I found the most interesting thread on math overflow all about <a href=\"http:\/\/math.stackexchange.com\/questions\/831022\/mathematical-research-of-pok\u00e9mon\">Pok&eacute;mon research<\/a>. <\/p>\n<p>The basic strategy of the game is that each play picks 6 Pok&eacute;mon from a stable of 718, and each Pok&eacute;mon has 4 out of 609  possible moves.  The opposing Pok&eacute;mon face off against each other one by one and have various levels of strength and vulnerability to attack.  So there truly are a finite number of strategies with two independent decision makers, meaning a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Nash_equilibrium\">Nash equilibrium<\/a> does exist. Of course this is a relatively gigantic space of play, so it&#8217;s pretty difficult to actually model the possibilities, and it&#8217;s not a sure thing that the Nash equilibrium will be what plays out.  <\/p>\n<p>Another fun aspect that makes the Pokemon game hard to model and predict is that you are in a game with <a href=\"https:\/\/en.wikipedia.org\/wiki\/Perfect_information\">imperfect information<\/a>.  Your opponent may know that you&#8217;re holding <a href=\"http:\/\/pokemondb.net\/pokedex\/charmander\">Charmander<\/a>, but your opponent has know way at face value to determine which moves you&#8217;ve chosen for him. <\/p>\n<p>The new version, Pok&eacute;mon Go, seems to be a bit less focused on an end point.  Instead, it appears that you just like crazy catching Pok&eacute;mon until you eventually level out and have a super powerful character that can do whatever he wants.\u00a0\u00a0In which case you would be the baller of the Poke world&#8230;but that is about it.  <\/p>\n<p>Business are also having some fun with the Pok&eacute;mon Go craze.  Apparently you can use Pokecoins to <a href=\"http:\/\/www.pcmag.com\/article\/346047\/pokemon-go-how-the-pokeconomy-is-changing-business-one-lur\">buy lures<\/a> which entice Pok&eacute;mon Go players into your brick-and-mortar establishment for the bargain price of <a href=\"https:\/\/twitter.com\/sebfung\/status\/752346058299215872\/photo\/1?ref_src=twsrc%5Etfw\">one dollar and 17 cents per hour<\/a>.  <\/p>\n<p>For some poor souls, registering an account has already been an exercise in game theory.  Pok&eacute;mon Go is so out of control popular that the number of people trying to resister every minute of every day has overwhelmed their servers beyond their capability.  The Pok&eacute;mon Go people have asked users to wait an hour and try again, but this of course, will never work and is a perfect example of a <a href=\"https:\/\/www.washingtonpost.com\/news\/monkey-cage\/wp\/2016\/07\/12\/cant-register-for-pokemon-go-game-theory-helps-explain-why\/#comments\">Tragedy of the Commons<\/a>.  <\/p>\n<div style=\"margin-top: 0px; margin-bottom: 0px;\" class=\"sharethis-inline-share-buttons\" ><\/div>","protected":false},"excerpt":{"rendered":"<p>This has been a weird week.
