Remember, if you are suffering in INTRACTABLE pain, narcotic use will help you to be NORMAL, not comatose!
The original 2nd-ASAM presented in this work should enable the hitherto very difficult, if not intractable, exact computation of all of the second-order response sensitivities (i.e., functional Gateaux-derivatives) for large-systems involving many parameters, as usually encountered in practice.
The normal trade union strike is a finite event joining two parties contesting over limited, if sometimes intractable, issues.
And although Maraniss could feel "a bit more energy" in Detroit during his many visits to do research, he concludes that the city's "structural problems remain enormous, if not intractable, and the recovery can never be called a success unless there are jobs and houses for the backbone of the city, the working middle class".
Our nation is seeing huge numbers of its citizens slide into actual — and virtually intractable, if we keep hold of President Bush's policies — poverty.
In this circumstance, MCS requires a potentially burdensome (if not computationally intractable) number of model evaluations to obtain a credible estimate of the global statistics.
The problem becomes computationally intractable if dynamic analysis is performed in the time domain, which is often necessary due to nonlinearities.
It is known that the problem of non-rigid structure from motion (NRSFM) is generally underconstrained and thus intractable, if each point of the object moves arbitrarily.
The ML approach would be infeasible if the spatial weights matrix is not row-normalized while the time effects are eliminated, and would be computationally intractable if there are multiple spatial weights matrices in the model; also, consistency of the MLE would require T to be large and not small relative to n if the fixed effects are jointly estimated with other parameters of interest.
Determining all of these interaction effects is intractable if the number of cell types involved is more than three or four, but nevertheless this issue exists and may be a source of error in a linear model that does not incorporate it.
