All patients had a significant improvement in ventilatory parameters at anaerobic threshold, along with a 44% Weber class improvement.
The primary end point was restricted to Canadian Cardiovascular Society angina class improvement to limit the number of patients exposed to a sham procedure.
In May 1954, SCB created a class improvement plan for the North Carolinas which included twenty-four 3 in/50 guns directed by six Mark 56s.
No difference in benefit was detected between the SR and the AF patients for NYHA class improvement or for ejection fraction.
Additionally, the patient's subjective well-being advanced decisively which was also reflected by a functional class improvement to NYHA II.
British Airways and Virgin Atlantic Airways set the modern standards for premium-cabin competition a few years ago as each tried to outdo the other with consecutive business-class improvements, especially in a battle over flat-bed seats in 2000.

Neighborhood search algorithms (alternatively called local search algorithms) are a wide class of improvement algorithms where at each iteration an improving solution is found by searching the "neighborhood" of the current solution.
