Query: Linear Inverse Problems with Norm and Sparsity Constraints   We describe two nonconventional algorithms for linear regression, called GAME
and CLASH. The salient characteristics of these approaches is that they exploit
the convex $\ell_1$-ball and non-convex $\ell_0$-sparsity constraints jointly
in sparse recovery. To establish the theoretical approximation guarantees of
GAME and CLASH, we cover an interesting range of topics from game theory,
convex and combinatorial optimization. We illustrate that these approaches lead
to improved theoretical guarantees and empirical performance beyond convex and
non-convex solvers alone.
