Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solutions algorithm » solution algorithm, evolution algorithm, evolutionary algorithm
df optimisation » _ optimisation, _ optimization, qoe optimization
mild solutions » time solutions
modified mild » modified male, modified seird, modified bi1
modified df » modified _, modified adam, modified bi1

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified mild solutions algorithm ) OR ( modified df optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified mild solutions algorithm ) OR ( modified df optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified mild solutions algorithm ) OR ( modified df optimisation algorithm ))*.
