3.The number of nodes for NOPRUNE up to eight agents were obtained from experiments, the rest can be
calculated using the formula [m]^{n}∕n! = (m + n- 1) ⋅…⋅m∕n!, where m represents the number of heterogeneous
role types and n is the number of homogeneous agents. [m]^{n} = (m + n - 1) ⋅… ⋅ m is referred to as a rising
factorial.
