A　Levy　search　strategy　based　chaotic　artificial　bee　colony　algorithm　(LABC)　is　proposed　in　this　paper.　The　chaotic　sequence,　global　optimal　mechanism　and　Levy　flight　mechanism　were　introduced　respectively　into　the　initialization,　the　employed　bee　search　and　the　onlooker　bee　search.　The　experiments　show　that　the　proposed　algorithm　performed　better　in　convergence　speed,　global　search　ability　and　optimization　accuracy　than　other　improved　ABC.
