In any semi-decent peer reviewed venue, you would cite a wide variety of papers that solve a similar or related problem or introduce a concept related to the method in the paper.
The related work section of a paper is one of the most important parts since it puts the research into context. By citing other work, the authors explain what has already been done, and what contribution their work makes.
A related work section should also illustrate the downsides, limitations, and differences of other cited research. Limitations of other works are often poorly understood since very few people have had the time to evaluate them beyond the initial experiments done before first publication.
Research is not simply about presenting new techniques but also understanding the trade-offs that arise when choosing different solutions to a problem.
