Perhaps you should try some spelling variations:
"game optimization algorithm" » "game optimization algorithms", "game optimisation algorithm", "game estimation algorithm", "stage optimization algorithm", "qoe optimization algorithm", "market optimization algorithm"
"d_ optimizer algorithms" » "d_ optimized algorithms", "d_ optimization algorithms", "_ optimized algorithms", "_ optimize algorithms", "_ optimise algorithms"
"one optimized algorithm" » "one optimized algorithms", "_ optimized algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("d_ optimizer algorithms") OR ("one optimized algorithm"))) OR ("game optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"d_ optimizer algorithms\") OR (\"one optimized algorithm\"))) OR (\"game optimization algorithm\"))".
• Removing quotes may allow a broader search: (((( d_ optimizer algorithms ) OR ( one optimized algorithm ))) OR ( game optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("d_ optimizer algorithms") OR ("one optimized algorithm"))) OR ("game optimization algorithm"))*.
