New algorithm solves quasar-convex optimization with constraints

Researchers have developed a new inexact accelerated proximal point algorithm for quasar-convex smooth functions with general convex constraints. This algorithm achieves an optimal first-order query complexity of $\widetilde{O}(1/(\gamma\sqrt{\varepsilon}))$, addressing an open problem in the field. The work also analyzes projected gradient descent and Frank-Wolfe algorithms within this constrained setting, providing the first analyses of first-order methods for quasar-convex smooth functions with general convex constraints.
