Abstract: Based on the analysis and summary of several improved binary search algorithm,we put forward a more highlyefficient and dynamic binary searcher based on node group,which is not only improved in the search efficiency,but alsoin the storage structure．This algorithm has achieved the dynamic real-time search,and it especially allows to insert and delete a group of elements．In addition,we discovered that the scheme is obviously better than the previous binary search algorithm in searching a large amount of data.

Key words: Binary search,Fibonacci search,Improved Fibonacci search,Dynamic binary searcher
