Perhaps you should try some spelling variations:
"modified total optimisation algorithm" » "modified total optimization algorithms", "modified total estimation algorithm", "modified total estimation algorithms", "modified global optimization algorithm", "modified thermal optimisation algorithm", "modified ti6al4v optimisation algorithm"
"modified objective optimized algorithms" » "modified objective optimized algorithm", "modified objective optimizer algorithms", "modified objective optimization algorithms", "modified objective optimal algorithms"

Try widening your search to All Fields.

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

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