This paper considers the locomotive assignment problem encountered during the planning of the operations of a freight railroad, which consists of providing sufficient motive power to pull a set of scheduled trains at minimum cost while satisfying locomotive availability and maintenance requirements. In 1997, Ziarati et al. proposed for this problem a heuristic branch-and-price approach that relies on a simple depth-first search strategy Nike Basket Blazer Mid Femme without backtracking. In this paper, we present an efficient backtracking mechanism that can be added to this heuristic branch-and-price approach. To do so, we propose and evaluate different branching methods that impose multiple decisions on locomotive routes at each branching node, including one decision that forbids one such route. Finally, we introduce different ways of computing an estimate of the best integer solution value that can be obtained from a branch-and-bound node. These estimates can be used to guide the backtracking process of a two-phase search strategy.

The current study investigated neuropsychologists’ beliefs and practices with respect to assessing effort and malingering by surveying a sample of NAN professional members and fellows (n = 712). The results from 188 (26.4%) returned surveys indicated that 57% of respondents frequently included measures of effort when conducting a neuropsychological evaluation. While a majority of respondents (52%) rarely or never provide a warning that Basket Nike Blazer effort indicators will be administered, 27% of respondents often or always Blazer Nike Pas Cher provide such a warning. The five most frequently used measures of effort or response bias were the Test of Memory Malingering (TOMM), MMPI-2 F–K ratio, MMPI-2 FBS, Rey 15-item test, and the California Verbal Learning Test. However, the TOMM, Validity Indicator Profile, Word Memory Test, Victoria Symptom Validity Test, and the Computerized Assessment of Response Bias were rated as most accurate for detecting suboptimal effort. These results and other findings are presented and discussed.
