Question:
131 Time to solve a math programming problem. IEEE Transactions presented a hybrid algorithm for solving a polynomial zero–one mathematical programming problem.
The algorithm incorporates a mixture of pseudo-
Boolean concepts and time-proven implicit enumeration procedures. Fifty-two random problems were solved by the hybrid algorithm; the times to solution (CPU time in seconds) are listed in the accompanying table and saved in the MATHCPU file.
a. Estimate, with 95% confidence, the mean solution time for the hybrid algorithm. Interpret the result.
b. How many problems must be solved to estimate the mean m to within .25 second with 95% confidence?
*c. Form a 95% confidence interval for the true standard deviation of the solution times for the hybrid algorithm.
Interpret the result.
