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 load evolution algorithm" » "modified load solution algorithm", "modified load evolutionary algorithm", "modified load convolution algorithms", "modified load evaluation algorithm", "modified global evolution algorithm", "modified co evolution algorithm", "modified adam evolution algorithm", "modified near evolution algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective optimisation algorithm") or ("modified load evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithm") OR ("modified load evolution algorithm")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified load evolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified load evolution algorithm"))*.
