Software crisis is a term used in the early days of software engineering. The term was used to describe the impact of rapid increases in computer power and the complexity of the problems which could be tackled. This was with regards to the difficulty in writing correct‚ understandable and verifiable_ computer programs_. VERIFIABLE:-With regards to hardware and software systems‚ a formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system

tutorial is intended to provide information on agents and agent technology to educate more of the software development and CHI community on the impact and nature of current Agent technology. By providing a reasonable backdrop for agents‚ this tutorial hopes to allow the student to pursue additional reading material with a more objective eye for that which is real and that which is hyperbole (hysteria?). 2 Objectives The tutorial student should leave with a general understanding of the structure

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

probabilistic approach to finding failure-causing inputs based on Bayesian estimation. According to our probabilistic insights of software testing‚ the test case generation algorithms are developed by Markov chain Mote Carlo (MCMC) methods. Dissimilar to existing random testing schemes such as adaptive random testing‚ our approach can also utilize the prior knowledge on software testing. In experiments‚ we compare effectiveness of our MCMC-based random testing with both ordinary random testing and adaptive

LARGE SCALE SOFTWARE DEVELOPMENT 1. What are the fundamental activities that are common to all software processes? a. Specification – defining what the system should do; b. Design and implementation – defining the organization of the system and implementing the system; c. Validation – checking that it does what the customer wants; d. Evolution – changing the system in response to changing customer needs. 2. List the 3 generic

provide presumed real world facts that systems are guaranteed to operate correctly. Although software processes have existed for many years now‚ domain knowledge should be applied throughout every phase of the software development process. An appreciation of the assumptions underlying software engineering can lead to a better understanding of the applicability of structure and quality of work produced. Software plays an important role in business decision-making‚ and because of its growing importance
