Perhaps you should try some spelling variations:
"using computational coder allocation problem" » "and computational coder allocation problem" (Expand search), "using computational code allocation problem" (Expand search), "using computational codes allocation problem" (Expand search), "using computational model allocation problem" (Expand search), "using computational coder location problem" (Expand search), "using computational power allocation problem" (Expand search), "using computational order allocation problem" (Expand search), "using computational over allocation problem" (Expand search)
"sensor and python python programming" » "sensor and pythons python programming" (Expand search), "sensor and piton python programming" (Expand search), "sensor and pitons python programming" (Expand search), "sensory and python python programming" (Expand search), "sensors and python python programming" (Expand search), "sensor based python python programming" (Expand search), "sensor in python python programming" (Expand search), "sensor on python python programming" (Expand search), "sensor api 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: "((\"using computational coder allocation problem\") OR (\"sensor and python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational coder allocation problem ) OR ( sensor and python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational coder allocation problem") OR ("sensor and python python programming"))*.
