The following three states occur in this order in the computation process of CCM, if appropriate rules and LODs are given. The state in which the probability distribution rapidly changes when a reaction occurs. 5.2 Conflict and Cooperation in CCM CCM-based systems can be put into two categories. Conflicting systems are called such because reactions does not cooperate toward that. Thus the GOD does not increase monotonically as shown in Figure 8 .
Some systems have little conflict while others have considerably more.
However, the definition of the degree of conflict is a task for the future. On the contrary, the GOD monotonically increases in a cooperative system. Examples of cooperative systems are the TSP system, the 0-1 Knapsack system and the sorting systems mentioned in Section 4.3 . The locality of computation can be controlled by adding catalysts to rules or composing two or more rules. Rules with less or more locality work differently because the value of IOD is used at reaction.
