Hi,
I have a constraint based problem that implements constraints as
explicitly defined threads. An if statement guards whether the
constraint is imposed or not. For example one of the constraints could
be something like:
thread
if B==2 then
<post some constraint>
end
end
My program isn't as simple as this and there IS a good reason why I'm
doing things this way :+), but it demonstrates the basic idea.
My question is this (although I can't think of a simplified example to
test it with); would the above code block prove more efficient like this:
thread
(B==2)=true
<post some constraint>
end
Here I'm assuming this thread would signal failure whenever B was not 2
and subsequently fail the space it was in.
In other words, are there any efficiency gains to be made by using
failure as a guard for the constraint rather than a logic conditional
statement? (Obviously I'm talking about a very large number of calls to
this thread.)
Regards
Mark
