A person or thing that finds solutions to problems; in computing, a program designed to find solutions to specific types of mathematical or logical problems.
From Latin 'solvere' meaning 'to loosen' or 'to release', through Old French 'soudre'. The agent noun 'solver' emerged in English in the 15th century, with computational solvers becoming prominent in the mid-20th century with the rise of computer science.
The original meaning of 'solve' was literally to untie or loosen knots, which beautifully captures what problem-solving feels like - working through tangled complications to find the loose end. Modern AI solvers can untangle problems in seconds that would take humans hours or days.
