摘要： A system and method for analyzing a computer program includes performing a static analysis on a program to determine property correctness. Test cases are generated and conducted to provide test output data. Hypotheses about aspects of execution of the program are produced to classify paths for test cases to determine whether the test cases have been encountered or otherwise. In accordance with the hypothesis, new test cases are generated to cause the program to exercise behavior which is outside of the encountered test cases.

摘要： A system and method for mining program specifications includes generating unit tests to exercise functions of a library through an application program interface (API), based upon an (API) signature. A response to the unit tests is determined to generate a transaction in accordance with a target behavior. The transaction is converted into a relational form, and specifications of the library are learned using an inductive logic programming tool from the relational form of the transaction.

摘要： A scalable, computer implemented method for finding subtle flaws in software programs. The method advantageously employs 1) scope bounding which limits the size of a generated model by excluding deeply-nested function calls, where the scope bounding vector is chosen non-monotonically, and 2) automatic specification inference which generates constraints for functions through the effect of a light-weight and scalable global analysis. Advantageously, scalable software model checking is achieved while at the same time finding more bugs.

摘要： A system and method for infeasible path detection includes performing a static analysis on a program to prove a property of the program. If the property is not proved, infeasible paths in the program are determined by performing a path-insensitive abstract interpretation. Information about such infeasible paths is used to achieve the effects of path-sensitivity in path-insensitive program analysis.

摘要： In accordance with aspects of the present principles, an over-approximation of reachable states of a hybrid system may be determined by utilizing template polyhedra. Policy iteration may be utilized to obtain an over-approximation of reachable states in the form of a relaxed invariant based upon template polyhedra expressions. The relaxed invariant may be used to construct a flowpipe to refine the over-approximation and thereby determine the reachable states of the hybrid system.

摘要： A system and method for inferring preconditions for procedures in a program includes formulating predicates based on inputs to a procedure, including formal arguments, global variables and external environment. Truth assignments are sampled to the predicates to provide truth assignments that lead to a feasible set of input values. Test cases are generated for testing the program in accordance with the truth assignments having feasible sets of input values. The truth assignments are classified to the predicates as providing an error or not providing an error.

摘要： A symbolic disjunctive image computation method for software models which exploits a number of characteristics unique to software models. More particularly, and according to our inventive method, the entire software model is decomposed into a disjunctive set of submodules and a separate set of transition relations are constructed. An image/reachability analysis is performed wherein an original image computation is divided into a set of image computation steps that may be performed on individual submodules, independently from any others. Advantageously, our inventive method exploits variable locality during the decomposition of the original model into the submodules. By formulating this decomposition as a multi-way hypergraph partition problem, we advantageously produce a small set of submodules while simultaneously minimizing the number of live variable in each individual submodule. Our inventive method produces a set of disjunctive transition relations directly from the software model, without producing a conjunctive transition relation—as is necessary in the prior art. In addition, our inventive method exploits the exclusive use of live variables in addition to novel search strategies which provide still further benefit to our method.
摘要翻译： 用于软件模型的符号分离图像计算方法，其利用软件模型独特的许多特征。 更具体地，根据本发明的方法，整个软件模型被分解成一个分离的子模块集合，并构建了一组单独的过渡关系。 执行图像/可达性分析，其中原始图像计算被划分为可以独立于任何其他方式对各个子模块执行的一组图像计算步骤。 有利地，本发明的方法在原始模型分解成子模块期间利用可变局部性。 通过将此分解形式作为多路超图分区问题，我们有利地产生一小组子模块，同时最小化每个子模块中的实时变量数量。 我们的创造性方法直接从软件模型产生一组分离过渡关系，而不产生结合过渡关系 - 这在现有技术中是必需的。 此外，除了新颖的搜索策略之外，我们的创造性方法还利用了实时变量的独家使用，这为我们的方法提供了更多的益处。
