Out, vaccine library is formed, and vaccine library is updated before next iteration starts；Secondly, optimal anti-from this 20
A vaccine antibody is extracted in body, the symbol in each gene position of vaccine antibody is taken as corresponding to gene in this 20 optimal antibody
The maximum symbol of probability of occurrence on position；According to inoculation probability PvThe new antibodies progress vaccine formed by genetic manipulation is chosen to connect
Kind, and compare the affinity of inoculation front and back antibody and antigen；The fitness that inoculation operation can improve antibody then receives inoculation, instead
Abandon be inoculated with；The probability P of immunity inoculationv=0.7；
Step 5, the evolution of vaccine library：
In promoting the evolutionary process of vaccine library using clone's genetic algorithm, clonal plant population is dimensioned to 100, each is anti-
Clone's quantity of body is calculated using formula (7)；Fixed aberration rate P is used in gene mutation operatorm=0.1；
During clone, the number q of each antibody duplicationiAs shown in formula
Wherein, if there is n antibody in initial population, i.e. A (k)={ a1,a2,…,an, the affinity of wherein antibody i is denoted as f
(ai), the capacity of population A ' (k) after cloning is set as Nc, take Nc>n；
Wherein operator [x] indicates the maximum integer no more than x；
Step 6, population recruitment：
After immune operation, the worst individual of affinity in population with quantity is replaced with highest 5 antibody of affinity in vaccine library；
It is random to generate 85% antibody that affinity is poor in population when not searching more excellent solution in continuous 20 generation.
