        bibo:abstract             "Optimisation algorithms are commonly compared on benchmarks to get insight  into performance differences. However, it is not clear how closely benchmarks  match the properties of real-world problems because these properties are  largely unknown. This work investigates the properties of real-world problems  through a questionnaire to enable the design of future benchmark problems that  more closely resemble those found in the real world. The results, while not  representative, show that many problems possess at least one of the following  properties: they are constrained, deterministic, have only continuous  variables, require substantial computation times for both the objectives and  the constraints, or allow a limited number of evaluations. Properties like  known optimal solutions and analytical gradients are rarely available, limiting  the options in guiding the optimisation process. These are all important  aspects to consider when designing realistic benchmark problems. At the same  time, objective functions are often reported to be black-box and since many  problem properties are unknown the design of realistic benchmarks is difficult.  To further improve the understanding of real-world problems, readers working on  a real-world optimisation problem are encouraged to fill out the questionnaire:  https://tinyurl.com/opt-survey" ;
