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