Perhaps you should try some spelling variations:
"based computation using locking problem" » "based computational using locking problem" (Expand search), "based competition using locking problem" (Expand search), "based compilation using locking problem" (Expand search), "based computations using locking problem" (Expand search), "based computation in locking problem" (Expand search), "based composition using locking problem" (Expand search), "based computation using docking problem" (Expand search), "based computation using packing problem" (Expand search), "based computation using loading problem" (Expand search), "based computation using stacking problem" (Expand search), "based computation swing blocking problem" (Expand search), "based computation using tracking problem" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using python python programming" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based computation using locking problem\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation using locking problem ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation using locking problem") OR ("using using python python programming"))*.
