Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"effective reading methods algorithm" » "effective gradient methods algorithm", "active reading methods algorithm", "effective learning methods algorithm", "effective making methods algorithm", "effective graining methods algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"effective reading methods algorithm\") OR (\"modified objective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( effective reading methods algorithm ) OR ( modified objective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("effective reading methods algorithm") OR ("modified objective optimization algorithm"))*.
