Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified seird optimization algorithm" » "modified seird optimization algorithms", "modified seird estimation algorithm", "modified seird estimation algorithms", "modified stage optimization algorithm", "modified network optimization algorithm", "modified near optimization 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: "((\"modified objective optimisation algorithm\") OR (\"modified seird optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) OR ( modified seird optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") OR ("modified seird optimization algorithm"))*.
