  Supersymmetry (SUSY) is a fascinating topic in theoretical physics, because
of its unique and counterintuitive properties. It is expected to emerge as new
physics beyond the standard model, and it is also a building block for
supergravity and superstring theory. A number of exact results obtained via
SUSY theories provide insights into field theory. However, the dynamics of many
SUSY theories are not yet fully understood, and numerical study of SUSY
theories through lattice simulations is promising as regards furthering this
understanding. In this paper, I overview the current status of lattice SUSY by
discussing its development in chronological order, and by reviewing some simple
models. In addition, I discuss the numerical verification of gauge/gravity
duality, which is one of the recent significant developments in this field.
