The binding process. (A) The movement trial drives S upward. Here the bond variables of S and T are empty (symbols {φ}). (B) Before the movement, S is checked to determine whether it may bind with T, by searching among the complex candidates. (C) If the table has a combination of single S and single T (S-T) simultaneously, a uniform random number ξ (0 ≤ ξ < 1) and the transition probability p₁ are compared. (D) When ξ <p₁, the movement is accepted.
