New improved error bounds for the linear complementarity problem.(English)Zbl 0829.90124

For the linear complementarity problem $\text{LCP}(M, q): Mx+ q\geq 0,\;x\geq 0,\;x(Mx+ q)= 0,$ with $$M$$ an $$R_0$$-matrix, i.e. the $$\text{LCP}(M, 0)$$ has zero as its unique solution, new error bounds are given. Various residuals used in these error bounds are discussed. In some sense the “best” residual is proposed.
