Az előadás címe: <b><i>Global Optimization</i></b><br>
<br>
<b><i>Abstract:</i></b> Global optimization aims at minimization of
a nonlinear objective function when no assumptions on unimodality
are included into formulation of the problem - many local minima may
exist. We will start this mini-course from introduction to global
optimization and discussion of deterministic covering methods
partitioning the feasible region.

Az előadás címe: <b><i>Simplicial Global Optimization<br>
<br>
</i></b><b><i>Abstract:</i></b> Although rectangular partitions
are used most often in global optimization, in this lecture we will
particularly discuss simplicial covering which has several
advantages. Applications benefiting from simplicial partitioning are
examined in detail: nonlinear least squares regression and pile
placement in grillage-type foundations.

Az előadás címe: <b><i>Optimization Based Visualization of
Multidimensional Data</i></b><b><i><br>
</i></b><br>
<b><i>Abstract:</i></b> The next lecture will focus on optimization
based visualization of multidimensional data. Multidimensional data
visualization enables exploratory data analysis involving heuristic
abilities of human experts when a set of objects is represented in a
low-dimensional space. In this lecture we consider one of the most
popular approaches known as multidimensional scaling, whose
essential part is optimization of a function possessing many
optimization adverse properties. Application areas of
multidimensional scaling vary from psychometrics to pharmacology.

Az előadás címe: <b><i>Non-convex Multi-objective Optimization</i></b><br>
<br></div><div><b>4. előadás</b><br></div><div>
<b><i>Abstract:</i></b> Real-world optimization problems usually
involve more than one criteria, what leads to solution of
multi-objective optimization problems. Multi-objective optimization
discussed in this lecture is a research area rich with various
approaches. Many methods convert the multi-objective optimization
problem into a set of single-objective problems. Apart from general
disadvantages of such approaches, in non-convex multi-objective
<br>
optimization even the scalarized single-objective optimization
problem is not easily solved - global
<br>
optimization must be used. As we saw in previous lectures, branch
and bound method can be used to solve global optimization problems,
and moreover it is possible to develop multi-objective branch and
bound algorithms which do not require scalarization of the problems.
In non-convex continuous multi-objective optimization such a
multi-objective branch and bound algorithm can find close
approximation of the Pareto front with predefined accuracy and in
discrete multi-objective optimization the exact Pareto-optimal set
can be found.
