Partial instances of such inference rules are almost the same as rewrite rules in the transformed LCTRS. In this paper, we aim at establishing a framework for simpler definitions and correctness proofs of transformations from programs into LCTRSs. To this end, for the transformation in previous work as an example, we show the existence of an injective function from configurations of a given program to terms, and reformulate the transformation by means of the injective function. The injective function enables us to make a one-to-one correspondence between single small-step transitions and reduction steps, and provides bisimilarity between the program and transformed LCTRS, resulting in a simpler correctness proof.</div></div>","PeriodicalId":48797,"journal":{"name":"Journal of Logical and Algebraic Methods in Programming","volume":"145 ","pages":"Article 101056"},"PeriodicalIF":0.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In those complex frameworks, optimizing code by hand is hard and time-consuming, making automated optimization particularly necessary. In order to automate optimization, a prerequisite is to find suitable abstractions to represent programs; for instance, algebras based on monads or monoids to represent distributed data collections. Currently, however, such algebras do not represent recursive programs in a way which allows for analyzing or rewriting them. In this paper, we extend a monoid algebra with a fixpoint operator for representing recursion as a first class citizen and show how it enables new optimizations. Experiments with the Spark platform illustrate performance gains brought by these systematic optimizations.</div></div>","PeriodicalId":48797,"journal":{"name":"Journal of Logical and Algebraic Methods in Programming","volume":"144 ","pages":"Article 101047"},"PeriodicalIF":0.7,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a continuation of the first steps towards the formal specification and analysis, in the high-performance language Maude, of signature schemes. We have adapted and improved a previous framework, originally aimed to formally specify and analyse post-quantum key encapsulation mechanisms. As a use case of the new framework, we specify an executable symbolic model of FALCON. On the symbolic model, we verify termination and fairness using LTL formulas with Maude's model checker. Furthermore, authentication, integrity and non-repudiation are analysed through invariant analysis. Integrity and non-repudiation hold, meanwhile, authentication does not hold in our symbolic model.</div></div>","PeriodicalId":48797,"journal":{"name":"Journal of Logical and Algebraic Methods in Programming","volume":"143 ","pages":"Article 101034"},"PeriodicalIF":0.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the expressions found in every program point, specifications for the encountered operations and functions are required. We propose a method for extracting these specifications from the Typeshed project, which contains a set of annotations for built-in and popular third-party libraries.

Communication is disciplined by global types: well-typed sessions are lock-free and their participants do follow the described protocols. A key issue is the composition of well-typed sessions, that we face via the <em>participants-as-interfaces</em> approach. We study session composition when a client session is connected to compliant server sessions, where compliance is naturally biased towards the client. We prove that a unique session can be constructed by transforming the interface participants of the client and the servers into gateways (that is, forwarders), if the sessions are well-typed and the compliance relation can be proved. The obtained session has a global type that can be derived from the global types of the composing sessions and the proof of compliance among the client and the servers. A novelty of our approach is that in the composition we only ensure Lock-freedom for the client session, disregarding this property for the server sessions, via a partial typing system. This choice strongly simplifies the construction of the gateways. We consider the present study as a further step toward a theory of <em>Open</em> MultiParty Session Types.</div></div>","PeriodicalId":48797,"journal":{"name":"Journal of Logical and Algebraic Methods in Programming","volume":"144 ","pages":"Article 101046"},"PeriodicalIF":0.7,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143092824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
