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