An improved adapative grouped individual reconstruction immune algorithm is presented,in allusion that immune algorithm has slow convergence velocity and may trap into local search.

Compared and analyzed the three groups of baby rabbit according to the aspects of their individual weight,daily increasing weight,survival rate,circumstance of ablactation and the quality of the young rabbit coat of hair.

The existence of overlapping individuals in the evolution populations means overlapping regions in the searching space,which makes the algorithm much less efficiently in exploiting new feasible region.
