% A feasible method for optimization with orthogonality constraints
%
% -------------------------------------------------------------------------
% 1. Problems and solvers
%
% The package contains codes for the following two problems:
% (1) min F(X), s.t., ||X_i||_2 = 1
%
%     Solver: OptManiMulitBallGBB.m
%
%     Solver demo: Test_maxcut_demo.m, solving the max-cut problem
%
% (2) min F(X), S.t., X'*X = I_k, where X \in R^{n,k}
%
%     Solver: OptStiefelGBB.m
%
%     Solver demo: test_eig_rand_demo.m, computing leading eigenvalues
