Baroi on ki algoritmro ijrochi amali gardonida tavonad, boyad on bo yagon tarz tasvir karda shavad. SHaklhoi nisbatan beshtar pahngardidai algoritmho matni, formulavi-matni, jadvali, blok-naq- shavi va barnomavi meboshand.
SHakli matnii algoritm imkoniyat medihad, ki algoritm ba vositai kalima va jumlahoi zaboni muqarrarii guftugui navishta shavad. Dar shakli formulavi – matnii algoritm marhalahoi on bo yorii formulahoi matematiki tasvir karda shuda, baroi sharhu ezohashon az matnho istifoda mebarand. SHakli jadvalii algoritm imkoniyat medihad, ki marhalahoi on dar satru sutunhoi jadval tasvir karda shavand.
Blok – naqsha tasviri grafikii sokhtori mantiqii algoritm meboshad, ki dar on har yak marhalai algoritm ba vositai yagon shakli geometrii muvofiq (blok) ifoda karda meshavad. Baroi nishon dodani samti idorakuni az tircha istifoda mebarand. Ba sifati blokho shaklhoi zerin istifoda meshavand:
SHakli barnomavii algoritm – in tabdili algoritm ba dasturi makhsusest (barnoma), ki kompyuter mahz dar asosi on korero ba anjom merasonad. Baroi ejodi barnomaho az zabonhoi barnomarezi (algoritmi) istifoda mebarand. Aslan barnomai kompyuteri – in algoritm dar zaboni kompyuter ast.
Halli masalai dilkhoh ittilooti peshaki dodashudaro talab menamoyad. Az in lihoz guftan mumkin ast, ki algoritm ravandi pay dar pay ba natijai zaruri tabdil dodani ittilooti ibtidoi ast. Hamchunin, dar khotir boyad nigoh dosht, ki ijrochi algoritmro rasman ijro mekunad va hamesha bo miqdori okhirnoki amalho saru kor dorad.
