As the PC-algorithm used by [ 7] provides bounds (a, b) for the estimated causal effects, we considered two options to facilitate comparisons with the other methods: an "optimistic" calculation, where we use the value max abs a, b)), and a more conservative "pessimistic" strategy, using the value min abs a, b)) if a and b have the same sign, 0 otherwise.
This leads to unnecessarily high power consumption of the heating module in case of a pessimistic control strategy.
The precise strategy correctly identifies all faulty processors while the pessimistic strategy isolates all faulty processors within a set containing at most one fault-free processor.
In this paper, we discuss fault diagnosis in an enhanced OTIS network, including both the precise strategy and pessimistic strategy under the PMC diagnostic model.
Two order sets (dominating set and dominated set generated by order relation) and three risk strategies (optimistic strategy, equable strategy, pessimistic strategy) are induced to construct the model and design the algorithm of ordered three-way decisions.
19 (2) A pessimistic type chooses the strategy that secures the best of all worst outcomes.
Bear Stearns also decided to unwind an aggressively pessimistic hedging strategy known internally as the "chaos trade," because of what the Journal said was a "fierce divide" among top executives at the firm.
When in doubt (no accurate knowledge of actual spatial resolution), the best strategy, therefore, is to use a pessimistic (i.e. probably too high) estimate for FWHM, e.g. 8 mm even if actual resolution might be 6 mm.
If 1 assumes a pessimistic scenario, the ICER of the F12-only+CUF-only strategy increased from $4,446/QALY to $29,053/QALY and the ICER of the F&M12+CUF&M increased from $45,056/QALY to $124,063/QALY.
It comprises six items assessing catastrophising as a pain-related coping strategy characterised by a feeling of being overstrained and a pessimistic future perspective.
