式中， 是保证算法有效迭代的最小挥发值，通过该式每次迭代完成后可减低路

In the formula, is the minimum volatilization value to ensure effective iteration of the algorithm. After each iteration through this formula, the volatilization speed of the pheromone on the path can be reduced, thereby speeding up the convergence process.

is the minimum volatilization value to ensure the effective iteration of the algorithm, which can reduce the evaporation speed of the informationin on the path after each iteration is completed, thus speeding up its convergence process.
