....R(3) 8 and R(k, l) o(R(k, l) while l 3 is fixed, where R(k, l) and R(k, l) are the corresponding o# diagonal numbers. Finally, we mention that other games inspired by Ramsey s theorem have been investigated in several forms. The reader is referred to, for instance, Beck [2, 3, 4, 5], Beck and Csirmaz [1] Erdos and Selfridge [7] and Seress [20] ....

....[94] studied the achievement game restricted to classical Ramsey theory, where both graphs G and H are complete. They showed that: The first player has winning strategy for the achievement game if G = K n , H = K k and 1 2 log 2 n and it is a tie if k 2(1 o(1) log 2 n. Beck and Csirmaz [30, 31, 32] generalized these to achievement games for uniform hypergraphs. Other studies on winning strategies can be found for example in [102, 140, 163, 161, 199] see also the survey on combinatorial games in general by Guy [139] Slany [232] has created an interactive java version of the graph Ramsey ....

....is on line in the strong sense that at the stage of defining the color of x i , we do not know which points will be x i 1 , x i 2 , x s . In fact, we do not know the set S itself. We now outline idea of the proof of Theorem 3. 2 (note that a similar idea was used in earlier papers [9, 10, 11, 12]) Let s suppose that # and k required by condition (3.2) exist. We first define an auxiliary family of big sets of size O(N 1 # ) By applying Theorem 3.4 to this family of big sets , we obtain a partial coloring g : X # red, blue, uncolored in time N # O(1) such that letting S = x ....

....Maker is guaranteed to have a winning strategy this argument is nonconstructive. The next natural question is can Maker win faster, i.e. can Maker win if N R(n; n) and, ultimately, what is the minimal number of moves needed for Maker to win the game. Using the weight function method, Beck [3] showed that Maker can win if N (2 ffl) n for n sufficiently large. By setting up an appropriate weight function, a weight is assigned to every Kn ae KN and Maker picks an edge (to be colored red) in order to maximize the total weight (i.e. sum of the weights of all Kn s) This winning ....

We now outline idea of the proof of Theorem 1. 3 (note that a similar idea was used in earlier papers [3, 4, 5, 6]) Let s suppose that # and k required by condition (1.5) exist.
