Gigantic rates of data production in the era of Big Data, Internet of Thing (IoT)/Internet of
Everything (IoE), and Cyber Physical Systems (CSP) pose incessantly escalating demands …

Approximate circuits are digital circuits that are intentionally designed in such a way that the
specification is violated in terms of functionality in order to obtain some improvements in …

The problem of developing an approximate implementation of a given combinational circuit
can be formulated as a multi-objective design problem and solved by means of a search …

Genetic improvement (GI) improves both functional properties of software, such as bug
repair, and non-functional properties, such as execution time, energy consumption, or …

Automatic defect detection on reflective surfaces is a compelling process. In particular,
detection of tiny defects is almost impossible for human eye or simple machine vision …

We have recently proposed approximate median filters (APMFs). They are based on the
sorting network and achieve acceptable image quality under low-cost hardware. In this brief …

High order mutation analysis of a software engineering benchmark, including schema and
local optima networks, suggests program improvements may not be as hard to find as is …

Today, the concept of approximation in computing is becoming more and more a “hot topic”
to investigate how computing systems can be more energy efficient, faster, and less …

Low power image and video processing circuits are crucial in many applications of computer
vision. Traditional techniques used to reduce power consumption in these applications have …

We use continuous optimisation and manual code changes to evolve up to 1024 Newton-
