What is an overlap in math?

In mathematics, computer science and logic, overlap, as a property of the reduction rules in term rewriting system, describes a situation where a number of different reduction rules specify potentially contradictory ways of reducing a reducible expression, also known as a redex, within a term.

Is valve overlap bad?

Any camshaft with a significant amount of overlap is not recommended for street-driven cars. The engine will have poor low-end power. For vehicles with power brakes, Low Vacuum also makes for a very hard brake pedal. Overlap also contributes to Exhaust Reversion, which isn’t good.
