Perhaps you should try some spelling variations:
"modified pulsed optimization algorithms" » "modified pulsed optimisation algorithm", "modified pulsed estimation algorithms", "modified pulsed estimation algorithm", "modified pulsed optimisation algorithms", "modified pulsed estimation algorithmss", "modified policy optimization algorithms"
"modified allocation optimization algorithm" » "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified allocation estimation algorithms", "modified location optimization 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 pulsed optimization algorithms") or ("modified allocation optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified pulsed optimization algorithms") OR ("modified allocation optimization algorithm")).
• Removing quotes may allow a broader search: (( modified pulsed optimization algorithms ) or ( modified allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified pulsed optimization algorithms") or ("modified allocation optimization algorithm"))*.
