    There are dozens of metaheuristic optimization methods inspired by the swarm behaviors of creatures in nature, plants, human-specific phenomena, events in scientific fields such as physics, mathematics, biology and chemistry. These methods are successful in certain problems but not in all problems. Therefore, new metaheuristic methods are suggested by researchers frequently. In this study, for the first time, six up-to-date metaheuristic optimization algorithms, namely Jellyfish Search Optimizer, Carnivorous Plant Algorithm, Giza Pyramids Construction Algorithm, Gradient Based Optimizer, Student Based Psychology Optimization and Tunicate Swarm Optimization, were compared by using 10 mathematical benchmark functions with 10, 30 and 50 dimensions. According to the results obtained, Student Based Psychology Optimization gave the best results in 7 out of 10 benchmark functions. It was observed that Gradient Based Optimizer gave the best results in 4 benchmark functions. Carnivorous Plant Algorithm and Tunicate Swarm Optimization showed the worst performance. In order to compare in terms of time, algorithms were run at 1000 iterations in 50- dimensional benchmark functions. When the average run times obtained are examined, it is seen that Jellyfish Search Optimizer and Tunicate Swarm Optimization are the fastest running algorithms. Carnivorous Plant Algorithm and Student Based Psychology Optimization were the slowest running algorithms.
