A new projection and contraction method for variational inequalities. (English) Zbl 1101.90393
Summary: Based on the projection method for solving variational inequalities proposed by M. V. Solodov and B. F. Svaiter [SIAM J. Control. Optim. 37, 765–776 (1999; Zbl 0959.49007)], we give a new projection and contraction method for solving these variational inequalities by contracting the projection region. It is demonstrated that our algorithm is globally convergent under mild conditions and is sublinearly convergent if in addition a projection type error bound holds locally. Preliminary computational experience is also reported.
