Game two. All right, to set up game two, we begin at the scenario, trying to determine some basic questions. What type of game it is, what things we have to move around and so on. So here they say there are three films, Greed, Harvest and Limelight. They're gonna be shown during a film festival held on Thursday, Friday and Saturday. Read full transcript
Each film has to be shown at least once. But never more than once on a single day. And every day has to have at least one film shown on it. The films are shown one at a time. And then we have some rules. We have three things to put in an order.
That makes this a sequencing game. That's not quite a simple sequencing game. Because the items that we have put in order, G, H, and L, well, they can repeat. Since you can have it one of them a day, and there's three days, that would allow you to show each film three times for a total of nine films. Almost certainly the rules are gonna narrow that down.
But we don't wanna import any bad assumptions into them before we get down there. Since it is a sequencing game, our basic sketch is gonna be a series of labelled slots. So Thursday, Friday and Saturday. We have a roster of G, H and L that we can call upon.
For each of those guys we need to use them at least once. And we need to do something to indicate that we could put more than one film on a given day. So the way I would do that. Put a little bit of space in between the slots. To indicate that I have room to put another slot off to the left or off to the right.
And it still count as the same day. When we get to the rules, we do realize that we need a new symbol. This game asked us to keep track of something that there aren't a lot of games that ask us to keep track of. And that is the idea of who is the last film shown on a day? Well, the first rule says, on Thursday Harvest is shown and no film is shown after it on that day.
So normally I would just put H on Thursday and call it a day. Pun not intended, maybe a little intended. But I need a symbol to indicate that I can't put anything after the H. So I'm gonna do that by just adding a bar right after the H. To say that's it, you don't get any more on that day. And I'm gonna get to use that symbol twice.
Because the next rule is pretty much the same thing as the first one. It's just about Friday. So on Friday, the last film has to be either G or L. And nothing else is allowed after it on that day. However, rule 2 does have an extra component that rule 1 didn't have. On Friday, it's either Greed or Limelight, but not both that show.
So I also need to indicate to myself that I can't have both G and L on Friday. So I'm going to symbolize that with a little no GL written underneath Friday. And when I get to rule three, on Saturday either Greed or Harvest, but not both is shown. And no film is shown after it on that day. So it's the same rule as the second rule, except on Saturday with G and H.
So either G or H is on Saturday No film is shown after it, and it can't be both G and H on Saturday. After you've written the rules into your shorthand, you do want to consider if there's any way that those rules can interact to create a deduction or a further inference. Something that could narrow your task down a little bit.
Unfortunately, here there isn't really much else we can do. Other than put the rules into shorthand. The rules don't really interact with each other. They're all just about the day that it's on. There's no crossover potential. All I'm gonna do is draw a box around my sketch.
So that I know that is where I left it when I left the rule. Now that is your master diagram. You wanna make sure to keep your master diagram separate from your other diagrams. Don't erase in it, don't write in it. If you need to write more diagrams, and you probably will, write them out to the side.
Using the master diagram as a template that you copy from. And when you're done with those little minor diagrams, label them, block them off so you know where they came from.
