The grid-based clustering algorithm is an efficient clustering algorithm, but the effect of the algorithm is seriously influenced by the size of the predefined grids and the threshold of the significant cells. Thus, in this paper, to reduce the influences of the size of the predefined grids and the threshold of the significant cells, we adopt deflect and conquer techniques to propose a new grid-based clustering algorithm, which is called Adaptable Deflect and Conquer Clustering (ADCC) algorithm. The idea of ADCC is to utilize the predefined grids and predefined threshold to identify the significant cells, by which nearby cells that are also significant can be merged to develop a cluster in the first place. Next, the modified grids which are deflected to half size of the grid are used to identify the significant cells again. Finally, the new generated significant cells and the initial significant cells are merged so as to offset the round-off error and improve the precision of clustering task. And we verify by experiment that the performance of our new grid-based clustering algorithm, ADCC, is good.
