Property testing is a subfield of theoretical computer science that studies algorithms deciding whether an object has a certain property or is far from any object having that property by performing a small number of queries to the object
The goal of property testing is to design efficient algorithms that can quickly distinguish between objects satisfying a property and objects far from satisfying the property without fully examining the entire object
