3. Background
4. Multirelation Def.
A multirelation on A is a subset of AP(A).
(P(A) is the power set of A)
An ordinary binary relation on A is a subset of AA In this talk, I will give the relationship between multirelations and Kleene algebras. An ordinary on the other hand, a multirelationIn this talk, I will give the relationship between multirelations and Kleene algebras. An ordinary on the other hand, a multirelation
5. e.g. Multirelation for game [Venema 03] Given
A the states of a game board
P?AA possible transition by player P
Q?AA possible transition by player Q
W?A the winnning sets of player P
Def. Multirelation R for player P
R={(a,X) | ?b. aPb and ?c. (bQc ? c?X)}
Prop.
If (a,W)?R, then player P can win at the next turn of a)
(a,W)?R+RR+RRR+? Iteration of multirelation ? Multirelation is used to analyse games. Multirelation is used to analyse games.
6. Kleene algebra (KA) algebraic structure (K,+,0,,1,*)
for regular languages
e.g.
K the binary relations on A
R* is the reflexive transitive closure of R
It is used to represent properties of the reflexsive transitive closure of a multirelation.
