Webb1 juni 2016 · The computational power required for finding its globally optimal solution is very high. To address this difficulty, the L0 norm operator is usually approximated by an Lp norm operator with the value of p being between 0 and 1 [ 1 - 3 ]. Webb[3,15,25,39]. When the considered vector norms are p norms, the power method can count on a very fundamental global convergence result which ensures convergence to the matrix norm A β→α foraclassofentry-wisenonnegativematrices A andforarangeof p norms.
