PS Logic Games Ch 3 rules Flashcards
Linear game
One of the variable sets chosen as the “base” and is diagrammed in a straight line, either horizontally or vertically, and the remaining variable sets are placed into slots above or next to the base
One-to-one relationship
Each variable fills exactly one spot
4 Main type of Linear Rules
1) Variable placement rules
2) Fixed position rules
3) Sequencing or relative placement rules
4) Conditional rules
Variable placement rules
Where a variable can or cannot be placed
Not Laws
Line through letter - physically notate where a variable cannot be placed
Dual Options
H/J - When there are only two possible variables that can be placed in a single slot
Split Dual Options
H/__ __ /H - When a single variable has only tow possible positions
Triple Option
“A/B/C” - When single space can contain only one of three variables
Higher numbers
to the right (ex: 3 is higher than 2, 2 is higher than 1, etc)
Lower numbers
to the left (ex: 1 is lower than 2, 2 is lower than 3, etc)
Ahead
to the right
Earlier

Before

Preceding

West

Behind

Later

After

Following

East

When grades are listed as the base,
grades listed to the LEFT are “higher” or “better”
Blocks
[Y Z] - Represent fixed spatial relationship, variables that are next to each other
Split-Blocks
[D __ E] 0 Indicate that the variables are separated by a fixed number of spaces
In the linear stream, day 1 is
“before” day 2
Spaces Ahead or Spaces Before
Count the spaces from one variable to the other
->__ E
1 day before
->__ __ E
2 days before
-> [D __ E]
D is two days before E
G __
1 group behind
G __ __
2 groups behind
G __ __ __
3 groups behind
Spaces between or Spaces separated by
Put the exact number of spaces between the two variables
[M __ __ __ L]
3 spaces between
Rotating Blocks
[S T]
[T S] - A fixed relationship where the order of the variables are not knows (ex: S and T are on consecutive days, but we don’t know which one is first)
Rotating Split-blocks
[Q __ __ R] and
[R __ __ Q] compacted
to: [Q/R __ __ R/Q] - Rule says that Q and R are separated by two days, but not which variable is first
Not-blocks
[Q/R] - a slash over the block - The Variables cannot be next to one another OR cannot be separated by a fixed amount of space
Not-block split blocks
[D / E] - slash through the space(ex: D is not inspected 2 days before E is inspected)
3 variables linked in a sequence like H > Q > R will always yield
six Not laws
