Let H be a real Hilbert space, K a nonempty subset of H, and \(T:K\rightarrow \mathit{CB}(K)\) a multi-valued mapping. Then T is called a generalized k-strictly pseudo-contractive multi-valued mapping if there exists \(k\in[0,1)\) such that, for all \(x,y\in D(T)\), we have \(D^{2}(Tx,Ty)\leq\|x-y\|^{2}+kD^{2}(Ax,Ay)\), where \(A:=I-T\), and I is the identity operator on K. A Krasnoselskii-type algorithm is constructed and proved to be an approximate fixed point sequence for a common fixed point of a finite family of this class of maps. Furthermore, assuming existence, strong convergence to a common fixed point of the family is proved under appropriate additional assumptions.
