Perhaps you should try some spelling variations:
"coder collocation pid algorithms in" » "power allocation pid algorithms in" (Expand search), "des collocations pid algorithms in" (Expand search), "and collocation pid algorithms in" (Expand search), "coder collocation grid algorithms in" (Expand search), "coder collocation and algorithms in" (Expand search), "coder collocation in algorithms in" (Expand search), "coder collocation simd algorithms in" (Expand search), "coder collocation pid algoritmos in" (Expand search), "coder collocation pid algorithms and" (Expand search), "coder collocation pid algorithms _" (Expand search)
"api pythons python python programming" » "api pitons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pythons piton python programming" (Expand search), "api pythons pitons python programming" (Expand search), "api pythons pytm python programming" (Expand search), "api python python python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder collocation pid algorithms in") OR ("api pythons python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder collocation pid algorithms in\") OR (\"api pythons python python programming\"))".
• Removing quotes may allow a broader search: (( coder collocation pid algorithms in ) OR ( api pythons python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder collocation pid algorithms in") OR ("api pythons python python programming"))*.
