Perhaps you should try some spelling variations:
"modified a optimization algorithms" » "modified a estimation algorithms", "modified a estimation algorithm", "modified a optimized algorithms", "modified _ optimization algorithms", "modified _ optimisation algorithms", "modified game optimization algorithms", "modified df optimization algorithms", "modified adam optimization algorithms"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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