Piecewise linear relationship between L1 norm objective functional values and L∞ norm constraint specifications

For a sparse optimization problem with an null null null null null L null null null 1 null null null null null norm objective function subject to an null null null null null L null null null ∞ null null null null null norm inequality constraint, this paper finds that there is a piecewise linear relationship between the null null null null null L null null null 1 null null null null null norm objective functional values and the null null null...
