“…Furthermore, the threads would be successively synchronized for the treatment via CPU scheduling. Moreover, the dynamic slicing criterion got for the such algorithm being the place S that's the declaration into the program, v represents the object or variable utilized in the targeted declarations, E represents the implementation hint with the enter i furnished dynamically at the working period [15]. Such an algorithm creates certain that the threads with high primacies are similarly treated via using the CPU via the simultaneous hanging as well as restarting of threads.…”

One of the issues with multi-threading in operating systems is the concurrency of operations or threads. In a multithreaded process on a single processor, the processor can switch execution resources between threads, enabling concurrent execution. Concurrency indicates that more than one thread is making progress, but the threads are not actually running simultaneously. The switching between threads occurs rapidly enough that the threads might appear to run simultaneously. In this paper, three related strategies for prioritizing multi-threading are presented: ACE-thread, Semaphore coprocessor, and the Concurrent Priority Threads Algorithm. The aim of this work is to enhance an existing prioritization algorithm, specifically the Concurrent Priority Threads Algorithm, by extending a dynamic slicing algorithm to prioritize multi-threading concurrently. The algorithm is designed to compute correct slices in multi-threading prioritization scenarios. Threads with the same highest priority can perform in a synchronized manner without encountering deadlocks. The C++ programming language is used to implement the extended algorithms. The improved algorithm achieved results that were 3% more accurate than the existing one. The outcomes of this work would facilitate the simultaneous execution of threads with the same priority, ultimately reducing waiting and processing times.

“…Other techniques focused on the representation of polymorphic objects in Java. This is the case of the JSysDG [202] and the SSLDG [128], mentioned at the beginning of this paper. Both graphs include a multiple-layer representation that contemplates Java programs at different levels: package level, class level, method level, and statement level.…”

“…The classic flow dependence definition was thought for variables that are atomically defined or used in a program statement, but has never been reconsidered to deal with object variables, which can be partially defined or used (by defining or using only one of its data members) in a statement. This representation error was inherited by later program representations derived from the JSysDG, such as the Sub-Statement Level Dependence Graph (SSLDG) [128].…”

“…We have observed that similar ad-hoc solutions have been proposed in the literature once and again to solve the same problem in different contexts. To cite some examples, the SDG has been extended with additional nodes to represent: objects [118,128,202], exceptions [6,62], for-loops [132], list comprehensions [181], composite data structures [72,108,123,186], etc. The need for these ad-hoc solutions are a clear symptom that the SDG should be generalised to account for all those problems.…”

We live in a society where digitalisation is present in our everyday life. We wake up with the alarm of our mobile phone, book our meetings in our digital calendar, save all our media in the cloud storage, and spend time in social networks almost daily. Every one of these tasks is run over a software Por último, pero no por ello menos importante, quiero agradecer a todos mis amigos, que han aguantado mis quejas sobre trabajar en la investigación durante nuestras conversaciones de bar todos estos años. Especialmente me gustaría agradecer a Amanda, por acompañarme durante el tramo final de esta etapa de mi vida, que cierra un capítulo que para nosotros no es más que el prólogo de nuestra historia.xiii
