step 101, obtaining n resistance values to be detected, randomly dividing the n resistances into m groups of l resistances to obtain a matrix A, wherein a is 1,1 -a m,l Representing the resistance of each resistor:
specifically in this embodiment, by dividing n=1000 resistors into 100 groups of 10 resistance tests each. The method for measuring the minimum difference of the average division combination of the irregular resistors can reach the maximum difference of 100 groups of resistors within 5 seconds and is optimized to be 0.1 ohm. Compared with the existing CGA algorithm, the method has extremely poor and running time greatly improved.
Step 102, summing the resistance values of each group, determining one resistor in two groups with the largest random exchange range after the sum of the resistance values of each group, and summing the resistance values of each group after random exchange again to obtain the range of the sum of the resistance values of each group, wherein the range is the maximum value of the resistance values and the difference value of each group; specifically, n=1000 resistance tests in step 101 are exemplified:
for n resistors, n=m×l, the n resistors are randomly divided into m groups of l resistors each.
We randomly assign these n resistors to a matrix a of m x/s:
each row of matrix a represents one grouping of l resistors. The sum of the resistance values of each group is
The resistance of the m packets is s= (S 1 ,s 2 ,...,s m )。

S2, judging the range and the range target: while range > = diff_expected:
p1:s p1 group with maximum resistance =max (S)/. There are multiple identical maximum rows, one is chosen
P2:s p2 Group with minimum resistance value of =min (S)/. If there are multiple identical minimum rows, one is chosen
The random exchange of one element in p1, p2 stops when the number of random exchanges is from 0 to the maximum, i.e., for i=0 to max_exchange.
Step S3, the pole difference obtained each time is compared with the last pole difference in a superposition mode to obtain a pole difference optimization result, and judgment is carried out, namely, the absolute value of the difference between if p1 and p2 is reduced:
s4, if the absolute difference value of the p1 and the p2 is reduced, updating S,
proceeding to the Break jump continuation step S2/continue while/,
otherwise, else:
continuing the random exchange of one element of p1, p2 for step S2/continue for/,
stopping the step S2/reaching the maximum exchange times when the random exchange times are from 0 to the maximum threshold value, reducing the gap failure,
the recovery of the values of p1, p2,
outputting an optimized result which does not reach the target,
and (5) ending.
Step S5, when the random exchange times are less than the maximum threshold value, the extremely bad target in the step S2 is: diff_expected has been reached, outputting the optimized result that reaches the goal
For the same hardware condition, the exchange times per second are relatively stable, the random exchange and the extremely bad exchange are gradually reduced, and the optimized stability is ensured.
And 103, performing repeated comparison on the range obtained each time and the last range to obtain a range optimization result.

I.e. if the very bad target in step S2 when the number of random exchanges has not reached the maximum threshold value up to: diff_expected has been reached and the result of the optimization that reached the target is output.
Further, the step of summing the resistance values of each group after random exchange to obtain the range of the resistance value sum of each group further includes: judging whether a plurality of resistor groups with the same resistance value exist in each group at the same time, and if so, selecting one resistor group with the same resistance value.
