Because of NP-hardness, exact method does not work for large size problems, so a Metaheuristic approach (differential evolution) is proposed for large size problems.
Because of the complexity of the problem, only small-size problems can be solved in reasonable time using exact techniques.
However, the user experience has not been satisfactory because of the size mismatch problem, i.e., customers often fail to choose the right size online.
Mr. Greenspan said that because of their size, a problem at Fannie Mae or Freddie Mac could threaten the financial system.
Obviously expectation will now be higher and fans will want a similar position, some teams have also had to cut their squad sizes because of financial problems, but I think we've kept a similar strength team, so a fifth-place finish again is very possible.
However, it seems unlikely that such study will ever be performed because of logistic problems of study size and patients noncompliance.
Three specimens were lost because of technical problems (very small size of harvested pulp tissue), and thus the final investigation group consisted of 56 specimens (among which 5 specimens correspond to the control group).
Because of problems of sample size and relative lack of diversity, previous studies often failed to give clear-cut results.
He was accepted into the Austrian national ski academy at age 15 but was dropped from the program within a year because of knee problems and his small size (50 kg; 110 lb).
Although the case 2 was considered as a medium-size problem, because of high complexity of the model and NP-hard nature of the problem (Shen et al. 2003), GAMS failed to find an optimal solution within the limited run time.
