@inproceedings{8195, abstract = {This paper presents a foundation for refining concurrent programs with structured control flow. The verification problem is decomposed into subproblems that aid interactive program development, proof reuse, and automation. The formalization in this paper is the basis of a new design and implementation of the Civl verifier.}, author = {Kragl, Bernhard and Qadeer, Shaz and Henzinger, Thomas A}, booktitle = {Computer Aided Verification}, isbn = {9783030532871}, issn = {1611-3349}, pages = {275--298}, publisher = {Springer Nature}, title = {{Refinement for structured concurrent programs}}, doi = {10.1007/978-3-030-53288-8_14}, volume = {12224}, year = {2020}, }
