Efficiency linear programming tests

Many linear programming efficiency tests proposed in the literature are (maybe intentionally) formulated in absurd ways equations without variables, variables that do not appear anywhere in the constraints, linear combinations, useless equations, and so on. 

The initial instrument qualification process is detailed and comprehensive and includes both software (computer programs used in data acquisition, analysis, and archiving) and hardware (pumps, detectors, injectors, etc.). Once the instrument is qualified then methods themselves are developed and validated. The development process includes the initial evaluation of the appropriateness of the test, which is often determined by the ability of the method to meet targeted method requirements or mandates (linear range, linearity, accuracy, quantitation limits, resolution, etc.). Once these fundamental requirements are met, the cost effectiveness and overall efficiency are reviewed. Upon acceptance, a developed method then goes through a validation process.
