Fig. 3. The concept of MCC (Sumari, 2010) approach. By combining the two definitions previously explained, we define “collaborative computation” as a calculation on quantities done by a group of agent or multiagent that works together to achieve common or joint goals (Ahmad, Sumari, & Zubir, 2009) as depicted in Fig. 2. In an MCC scheme, each agent in the collaborative framework performs its own tasks to achieve its own goals. The goals achieved by each agent actually are partial parts of joint goal, which is the combination of partial goals. In simple word, the system is given a problem along with the goal that has to be achieved. The problem is then divided into several sub-problems that have to be solved by the agents. In achieving the sub-goals, the agents perform computation in parallel. The achieved sub-goals are then combined to become a single comprehensive goal that is called as joint goal (Sumari & Ahmad, 2009). c.

As previously mentioned in earlier section, the genes regulated by GRS will be represented by agents that will be working together in MCC paradigm. The experiments and the results delivered in this section are taken from (Sumari, 2010). We use data from (Zubir, 2009) namely yeast25-cho database as presented in Table 2. In this database, there are 25 genes from ACE2 to SIC1 as listed in column 1 with an interaction time interval from t-1 to t-17 or 17t times as shown in line 1. In order to give a view on the challenge in obtaining the knowledge regarding what genes are expressed in a given sample as well their behavior in a certain interaction time, the complexity of the data given in Table 3 is depicted in Fig. 6 and Fig. 7. The expressiveness of individual genes in 17t of interaction time is presented in Fig. 6, while the genes behavior in 17t of interaction time is presented in Fig. 7. The challenge in this case is to obtain knowledge from this phenomenon to answer the questions raised in Section 1.

\ multi-agent system (MAS) is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems which are difficult or impossible for an individual agent or monolithic system to solve. Agent systems are open and extensible systems that allow for the deployment of autonomous and proactive software components. Multi-agent systems have been brought up and used in several application domains.
