Perhaps you should try some spelling variations:
"modified static optimisation algorithms" » "modified static optimisation algorithm", "modified static optimization algorithms", "modified static estimation algorithms", "modified stage optimization algorithms", "modified stochastic optimization algorithms"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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