<p style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;"><span lang="en-GB">This session invites abstracts that address the development of optimization techniques for non-standard multiobjective problems. The features of such problems
might include (but are not limited to) the following:</span></p>
<p lang="en-GB" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</p>
<ul style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<li>
<p><span lang="en-GB">Instead of evaluating the objective and constraint functions by computational means, the execution of</span><span lang="en-GB"><strong>physical experiments in the real world</strong></span><span lang="en-GB"> (i.e., cosmetics, detergents,
pharmaceuticals, wind tunnel experiments, taste experiments, to mention a few) is required. Such experimental problems may be subject to time-consuming and expensive evaluations, changing variables or objectives (e.g. due to an updated problem formulation).
Moreover, the evolution may be affected by interruptions or unavailable resources, and the experimental equipment may dictate some of the algorithm setup choices such as population size.</span></p>
</li></ul>
<ul style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<li>
<p><span lang="en-GB">The objective and/or constraint functions are </span><span lang="en-GB"><strong>heterogeneous</strong></span><span lang="en-GB"> in the sense that some functions take longer to be evaluated than others, or are more complex to optimize
or satisfy than others due to differing landscape structures, feasible regions and borders. Such problems may lead to missing function values and introduce difficulties in converging to optima with respect to some of the objective functions and/or satisfying
some of the constraints.</span></p>
</li></ul>
<ul style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<li>
<p><span lang="en-GB">The 'objective' functions include </span><span lang="en-GB"><strong>subjective criteria</strong></span><span lang="en-GB">, such as taste or comfort. Expert or crowd-sourced evaluations are needed.</span></p>
</li></ul>
<ul style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<li>
<p><span lang="en-GB">The input and preferences of several disciplines (e.g. aerodynamics and structural input in an aircraft design problem) needs to be accounted for to make optimal decisions in a </span><span lang="en-GB"><strong>multidisciplinary optimization
environment</strong></span><span lang="en-GB">. Challenges in such problems include the intelligent combination of different preferences, shared variables and objectives, and ensuring consistency in the decision-making process.</span></p>
</li></ul>
<p lang="en-GB" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">
<br>
</p>
<p style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;"><span lang="en-GB">We encourage submission of abstracts describing new concepts, strategies, challenges and decision-making techniques in or for non-standard multiobjective problems.
In addition, we are interested in application studies discussing the power and applicability of these novel methods to real-world problems.</span></p>
