What is argmin?

gamma_t = argmin_{gamma in |R} || r_{t-1} - x_{j_t} gamma ||. 3: * Set new residual r_t = r_{t-1} - x_{j_t} gamma_t if (||r_t|| = 0) stop. NOTES: - can add ... Oct 28, 2021 ... Is there a way to perform an argmax on a subset of a vector determined by a bitarray. This bitarray tells whether the index should be considered or not. Dec 1, 2019 ... I was playing with ArgMin but I'm not sure how to use it for constrained optimization. For example, ArgMin[x^2, x] returns 0 as expected.

The global argmin occurs at x = 1. The derivative of the function is not zero at this point. Constrained optimization problems cannot be solved by finding roots. ... bidual of (6), as: {x∗. +, x∗. −, z∗, g∗} = argmin. {x+,x−,z,g} α>g + β. > z s.t..
