Before revision:  This paper presents OpenMPL [1], an open-source multiple patterning layout decomposition framework, with  efficient implementations of various state-of-the-art algorithms . Experiments are conducted on widely-recognized benchmarks and promising results are demonstrated .
After revision:  This paper presents OpenMPL [1], an open-source multiple patterning layout decomposition framework, with well-separated peripheral processing and the core solving steps. We demonstrate the flexibility of the framework with efficient implementations of various state-of-the-art algorithms . Experiments are conducted on widely-recognized benchmarks and promising results are demonstrated .
