+In the conclusion, you should summarize what was achieved by the thesis. In a few paragraphs, try to answer the following:
 \begin{itemize}
 \item Was the problem stated in the introduction solved? (Ideally include a list of successfully achieved goals.)
 \item What is the quality of the result? Is the problem solved for good and the mankind does not need to ever think about it again, or just partially improved upon? (Is the incompleteness caused by overwhelming problem complexity that would be out of thesis scope\todo{This is quite common.}, or any theoretical reasons, such as computational hardness?)

 \xxx{Abstracts are an abstract form of art. Use the most precise, shortest sentences that state what problem the thesis addresses, how it is approached, pinpoint the exact result achieved, and describe the applications and significance of the results. Highlight anything novel that was discovered or improved by the thesis. Maximum length is 200 words, but try to fit into 120. Abstracts are often used for deciding if a reviewer will be suitable for the thesis; a well-written abstract thus increases the probability of getting a reviewer who will like the thesis.}

 %  - for additional flexibility (e.g. multiple reference sections, etc.),

+%    with numeric citations. Additionally you can use a style like
+%    `numeric-comp` that compresses the long lists of citations such as
+%    [1,2,3,4,5,6,7,8] to simpler [1--8]. This is especially useful if you plan
+%    to add tremendous amounts of citations, as usual in life sciences and
+%    bioinformatics.
+%  - if you don't like the "In:" appearing in the bibliography, use the
+%    extended style (`ext-numeric` or `ext-alphabetic`), and add option
+%    `articlein=false`.
