Before revision:  In the (standard) centralized setting, Bansal and Umboh [BU17] gave an O(\alpha)-approximation LP rounding algorithm   .
After revision:  In the (standard) centralized setting, Bansal and Umboh [BU17] gave an O(\alpha)-approximation LP rounding algorithm , which translates into a near-linear time algorithm using general-purpose approximation results for explicit covering LPs .
