  • 摘要:In ar­ti­cle the prob­lem of de­sign­ing of the per­fect hash-ad­dress­ing for a con­stant set of keys is in­ves­ti­gated. The al­go­rithm of de­sign­ing of the per­fect hash-ad­dress­ing as hi­er­ar­chi­cal sys­tem of Boolean func­tions is de­vel­oped. The al­go­rithm al­lows to sig­nif­i­cant re­duce of vol­ume of com­put­ing re­sources which is nec­es­sary for de­sign of the per­fect hash-trans­for­ma­tion with the pre­scribed limit of hash-func­tion com­plex­ity. The analy­sis has shown the ad­van­tages of pro­posed per­fect hash-ad­dress­ing de­sign­ing al­go­rithm in com­par­i­son to known al­go­rithms of this prob­lem de­ci­sion.
