Benchmarking optimization software with performance profiles
Are performance profiles a tool for benchmarking and comparing optimization software?
Abstract.
We propose performance profiles — distribution functions for a performance metric — as a tool for benchmarking and comparing optimization software.
We show that performance profiles combine the best features of other tools for performance evaluation.
What is a performance profile in linear programming?
A performance profile reflects the performance only on the data being used, and thus it is important to understand the test set and the solvers used in the benchmark. 6.
Case Study:
Linear Programming Performance profiles can be used to compare the performance of two solvers but per- formance profiles are most useful in comparing several solvers. What tools are used to evaluate performance?
The quantities of data that result from benchmarking with large test sets have spurred researchers to try various tools for analyzing the data.
The solver’s average or cumulative total for each performance metric over all problems is sometimes used to evaluate performance [1,4,6].
Why is benchmarking of optimization software important?

Introduction The benchmarking of optimization software has recently gained considerable visibility.
Hans Mittlemann’s work on a variety of optimization software has frequently un- covered deficiencies in the software and has generally led to software improvements.
Virtual machine used by Android for executing Java apps
Dalvik is a discontinued process virtual machine (VM) in the Android operating system that executes applications written for Android.
Dalvik was an integral part of the Android software stack in the Android versions 4.4 KitKat and earlier, which were commonly used on mobile devices such as mobile phones and tablet computers, and more in some devices such as smart TVs and wearables.
Dalvik is open-source software, originally written by Dan Bornstein, who named it after the fishing village of Dalvík in Eyjafjörður, Iceland.
Tendency of software to fail due to external changes or prolonged operation
In software engineering, software aging is the tendency for software to fail or cause a system failure after running continuously for a certain time, or because of ongoing changes in systems surrounding the software.
Software aging has several causes, including the inability of old software to adapt to changing needs or changing technology platforms, and the tendency of software patches to introduce further errors.
As the software gets older it becomes less well-suited to its purpose and will eventually stop functioning as it should.
Rebooting or reinstalling the software can act as a short-term fix.
A proactive fault management method to deal with the software aging incident is software rejuvenation.
This method can be classified as an environment diversity technique that usually is implemented through software rejuvenation agents (SRA).
