Smart healthcare is revolutionizing the world by providing faster diagnosis and therapeutics. This technology is made feasible with sophisticated infrastructures that are made available everywhere. For instance, the early detection of Parkinson’s disease in the elderly and autism in children will pave the way for a better world and a better future.

Several healthcare systems are targeted towards these applications, which requires reliability. On the other hand, the systems designed should be a universal solution, making it viable for practice among a variety of end users. Recent hot topics such as IoT, Big Data, Cloud Computing, and Artificial Intelligence help to enable healthcare to become intelligent and realizable. The IoT enables data collection, Big Data provides data analysis, Cloud Computing offers computing, and Artificial Intelligence empowers predictive analytics. Thus, intelligent health care systems are expected to make a huge difference in the medical field in the near future. Keeping these virtues in mind, optimization algorithms also play a crucial role in data delivery to end users.
