Nonmonotone Adaptive Barzilai-Borwein Gradient Algorithm for Compressed Sensing
We study a nonmonotone adaptive Barzilai-Borwein gradient algorithm for l1-norm minimization problems arising from compressed sensing. At each iteration, the generated search direction enjoys descent property and can be easily derived by minimizing a local approximal quadratic model and simultaneous...
