In this example, x 1 =2 and the tentative assignment x 2 =1 is considered. Forward checking only checks whether each of the unassigned variables x 3 and x 4 is consistent with the partial assignment, removing the value 2 from their domains. The simpler technique for evaluating the effect of a specific assignment to a variable is called forward ...

C3 superclass linearization is an algorithm used primarily to obtain the order in which methods should be inherited in the presence of multiple inheritance. In other words, the output of C3 superclass linearization is a deterministic Method Resolution Order ( MRO ).
A (complete) feature freeze, in which all work on adding new features is suspended, shifting the effort towards fixing bugs and improving the user experience. The addition of new features may have a disruptive effect on other parts of the program, due both to the introduction of new, untested source code or resources and to interactions with ...
