Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
method algorithm » mom algorithm
df optimisation » _ optimisation, _ optimization, qoe optimization
control method » control methods
mode control » case control, mimo control
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 df optimisation algorithm ) OR ( mode control method algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified df optimisation algorithm ) OR ( mode control method algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified df optimisation algorithm ) OR ( mode control method algorithm ))*.
