Answer to Question 1

A poorly scaled modelone in which the parameters of the objective and constraint functions differ by several orders of magnitude may cause round-off errors in internal computations or error messages such as The conditions for Assume Linear Model are not satisfied. Experts often suggest that the values of the coefficients in the objective function and constraints, as well as the right-hand sides, should not differ from each other by a factor of more than 1,000 or 10,000.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
