The '''α-algorithm''' is an algorithm used in [[process mining]], aimed at reconstructing causality from a set of [[sequence of events|sequences of events]].
It was first put forward by [[Wil van der Aalst|van der Aalst]], Weijters and Măruşter.<ref>van der Aalst, W M P and Weijters, A J M M and Maruster, L (20032004). "Workflow Mining: Discovering process models from event logs", ''IEEE Transactions on Knowledge and Data Engineering'', vol 16</ref> Several extensions or modifications of it have since been presented, which will be listed below.
 
It constructs [[petri nets|P/T nets]] with special properties ([[workflow net]]s) from event logs (as might be collected by an [[Enterprise resource planning|ERP]] system). Each transition in the net corresponds to an observed task.
