Abstract Insight problem solving using heuristics is a promising approach of artificial intelligence that is based on Gestalt research on cognition. The first known story that link insight problem with heuristics is about Archimedes. ‘Insight’ can mean the profound understanding of a field of study, but we will restrict it to the sudden discovery of how a problem works. Insight is usually symbolized by a glowing light bulb to stress the sudden illumination of the insight. This thesis tries to answer the following questions: Can a simple problem become an insight problem? And how? Can one type of insight problems be transformed to another? Intuitively, can heuristics help in solving insight problems? What are the proofs both theoretically and practically ? What are the main sources of heuristics? Can we reach a heuristic generator? First, the thesis investigates an example for mathematical insight problem using symmetry, another example for verbal insight problem by trying to solve twins problem using logic programming languages, and an example for spatial insight problem by trying to solve optical illusion. The thesis also introduces an opportunity for applying insight in braincomputer interaction (BCI). The Pied Piper story inspired us to devise new heuristics for interfacing human motor system (HMS) using brain waves. By combining head helmet and LumbarMotionMonitor (LMM) and distinguishing between knowledgeable and not knowledgeable signals, it is possible to produce solutions for handicaps. Finally, the thesis proposes many nature-inspired metaheuristic optimization algorithm in different fields such as social networks, data mining, robotics, and neuroscience. Let us present a couple of them: There are two patterns of random walks: Brownian movement is associated with abundant preys and Lévy flight is associated with sparser or unpredictably distributed preys. With apparent potential capability, Lévy flight is applied to optimal search. Hoopoe Heuristic (HH) generates random moves using Lévy-Flight. After a while, the Hoopoe Heuristic changes its behavior by generating random moves using Ground-Probing. This may be interpreted by the level of experience a hoopoe has after a time in investigating the landscape. It outperforms other algorithms, with 100% optimality and less running time on standard test functions. There is a need for new metaphors from immunology to flourish the application areas of Artificial Immune Systems. A metaheuristic called Obesity Heuristic derived from advances in obesity treatment is proposed. The main forces of the algorithm are the generation omega-6 and omega-3 fatty acids. The algorithm works with Just-In-Time philosophy; by starting only when desired. A case study of data cleaning is provided. With experiments conducted on standard tables, results show that Obesity Heuristic outperforms other algorithms, with 100% recall. This is a great improvement over Genetic algorithms. |
