Left recursion occurs when a string can be decomposed into another string and a suffix, which can cause naive recursive parsers to loop indefinitely.

Many functional programmers optimize tail recursions to improve performance and avoid stack overflows.

The paper presented a co-recursive specification of the stream generator that made reasoning about infinite data structures simpler.

Many recursive functions can be optimized using memoization to avoid redundant computations.

To explain the sequence clearly, the professor introduced a recursive definition that starts with a base case and specifies how each subsequent term is formed.

The project's name, GNU, is a well-known example of a recursive acronym that playfully references itself.

When optimizing for performance, you should be careful with a recursive function that allocates large data structures on each call.

The tail recursive implementation eliminated the stack overflow for large inputs.

Researchers proved that the recursively enumerable set of valid program outputs can be produced by a deterministic enumerator that eventually lists every output.

The researcher proved that the function is primitive recursive by explicitly constructing it from the zero function, the successor function, and the projection functions using only a finite number of compositions and recursive steps.
