search for: unchosen

Hi there, I'm new working with R and I am trying to find the unchosen set of islands that are closer to all the possible combination (of 2 out of 13) of a set of chosen islands. In other words, if I have a set of 13 islands (1, 2, ...13) and choose all the possible combination of 2 islands (1-2, 1-3,...12-13) for each chosen pair of islands which of the unchosen isla...

The transformation in LibCallSimplifier::replacePowWithSqrt with respect to -Inf uses a select instruction, which based on the observed behaviour, incorporates the side effects of the unchosen branch. This means that (for pow) a call to sqrt(-Inf) is materialized. Such a call is specified as having a domain error (C17 subclause 7.12.7.5) since the operand is less than zero. Contrast this with pow(-Inf, 0.5), which is specified by C17 subclause F.10.4.4 as having a result of +Inf (indicat...
