… Therefore, this study proposes an algorithm of minimum incremental pattern backtracking
(MIPB) that is superior to IPB in time complexity. Experiments are conducted on an extended …

… with patterns). This is used in our two-level algorithm which we call Pattern Backtracking (PBT)…
Its upper level implements a tree search in the space of patterns (thus not fixing user …

… issue of balancing the performance and cost in pattern backtracking (PB) technique for
workflow satisfiability … was enforced in time on partial pattern solutions to strengthen pruning by …

… Pattern Backtracking (IPB) with its technique of k assignment is the preferred approach to
Workflow Satisfiability (WS) solving. However, for" under-constrained" instances, its pattern …

… Pattern Backtracking Algorithm The theoretical running time of the basic pattern algorithm
and, as we will see below, the pattern backtracking algorithm are O∗(2k log k) and thus are …

… workflow satisfiability problem (WSP) asks whether there exists an assignment of authorized
users to the steps in a workflow … our FPT algorithm and two numbers: the number of patterns …
