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