Often, such systems that are so complex that a symbolic approach to falsification is beyond the ability of existing solvers. We present two recent promising approaches to falsification based on the ideas of trajectory robustness and trajectory splicing.<\/p>\n<p>We show that the use of trajectory robustness can replace the standard Boolean interpretation of temporal logic properties with a real-valued interpretation that can guide the search for falsifying inputs.  Furthermore, we present the idea of trajectory splicing that searches over multiple, possibly disconnected trajectory segments rather than a single trajectory. We present some promising results using our approach and discuss open challenges that will drive future research.<\/p>\n<p>Note: All relevant concepts will be explained during the talk. Joint work with Aditya Zutshi (U. Colorado Boulder), Georgios Fainekos (Arizona State University), Jyotirmoy Deshmukh and James Kapinski (Toyota Technical Center).<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this talk, we address the problem of falsifying properties of complex cyber-physical sytems that model the interactions between a discrete controller and a continuous physical environment.
