Based on recent work with Hui Luo and with Ricardo Medina as well as an active project, I'll show that scattering amplitude (integrands) for quite general matter content and in principle quite general loop order can be obtained systematically from linear algebra with minimal physical input. As applications, I'll show novel structure in loop level gluon and graviton amplitudes and a derivation (in some cases) of the BCJ and KLT relations.
