8Property 1 Convergence of the MaxBet Algorithm
9Property 2 Necessary Condition of Convergence
103. Motivation and results
1. MaxBet Algorithm depends on the starting
vector
2. MaxBet algorithm does not guarantee the
computation of the global solution of SMP
113. Motivation and results an example

133. Motivation and results Two Questions
Q1. How can we know that the solution computed
by the Maxbet algorithm is global or not ?
Q2. When the solution is not global, how can we
reach using this solution the global solution ?

1. w is block-normed vector
20 1. w is block-normed vector
w is better solution than u
212. w is not block-normed vector 2.1. w is not
block orthogonal to u
v is better solution than u
22w is not block-normed vector 2.2. w is block
orthogonal to u
v is better solution than u
