Setting aside peculiarly moral reasons, common sense suggests that ordinary practical reasons exhibit a high degree of agent-relativity.
Obviously, the number of agents in each group and the degree of agents change dynamically as the network evolves.
We measure agent-to-agent ties by preference correlation using the contribution degree of one agent to another and the preference similarity degree between two agents.
Hereafter the in/out-degree correlation can be roughly identified with parameter (alpha ) when (alpha in [0,1]) as an increase in such parameter corresponds with an increase in the similarity between the out-degree and in-degree of agents.
Average payoff smoothes out possible differences in the degrees of agents, and in several aspects may simulate real-world situations better than non-averaged payoff, since in real-world situations agents usually have to observe a cost of maintaining a contact with their neighbors [39] [41].
Following that, as an important innovation, confidence level is introduced to quantify the degree of the agent's risk aversion, and the effects of the agent's attitude toward risk on the optimal contract and the principal's income are taken into account.
Equilibrium water content of the hydrogels was investigated as a function of the hydrophilicity of the polymers and the degree of crosslinking agent, and the influence of pH on the swelling behaviour of the hydrogels was determined.
For example, lymph node density on contrast-enhanced CT images reflects both tissue perfusion and degree of contrast agent diffusion in the tissue interstitium.
With increasing the content of the degree of crosslinking agent (from 2.0 to 4.0 wt.%) the mechanical properties of hydrogels are improving, as is clearly seen from the results in Figures 3(a) and 3(b).
Moreover, by introducing DSC technology, it avoids the well known problem of 'explosion of complexity' that conventional backstepping method suffers from along with the increasement of the degree of individual agents.
If, instead, (alpha =1) then an agent with twice the out-degree of another agent is selected twice as often.
