…th bound scaling, fix new conditional major computation, fix new constant and no perturbation for scaling
…ration count, add more debug prints
handle has restarted or not logic handle all restart metrics update (last error, best primal weight...) updated all restart method to know if has restared Fixes: handle no average restart checking if never restart to average removed useless plus one Fix scale and unscale logic fix halpern update weight update reafctor sum bounds since used in initial primal weight and fix min iteration restart issue fix major iteration issue correctly init primal and dual to 0 in localized duality gap removed useless convergeance variable Add new way to compute the convergeance information
