Which of the following is categorized as a type of intelligent technique?

Case-based reasoning is categorized as a type of intelligent technique because it utilizes past experiences to solve new problems. This method allows systems to take previous cases or scenarios—along with their outcomes—and apply similar reasoning to address current issues. The primary advantage of case-based reasoning is its reliance on historical data and experiences, enabling it to make informed decisions based on situations that have been encountered before.

In contrast, knowledge networks typically focus on the organization and sharing of knowledge in a structured manner, mainly enhancing communication and collaboration rather than direct problem-solving techniques. Computer-aided design is primarily a tool for design and engineering tasks, helping professionals create precision drawings and designs. Virtual reality modeling language is a markup language used to create 3D interactive graphics, particularly in VR environments, but it does not inherently involve the intelligent problem-solving capabilities that characterize intelligent techniques. Therefore, the selection of case-based reasoning as the type of intelligent technique in this context is well-founded, as it embodies the essence of leveraging knowledge from past cases for effective decision-making.
