PhD scholarship in Diversifying Heuristics for Stochastic Optimization Problems – DTU Management
Kgs. Lyngby, Denmark
Job Description

We are looking for an ambitious candidate for a PhD project to focus on development of heuristics for stochastic optimization.
You will be responsible for developing fast heuristics or MIP-models for solving two-stage optimization problems, such that many alternatives can be investigated.
As part of the PhD you will be following advanced courses to extend your skills, implement and test algorithms, and learn to write scientific papers. 
Research area and project description
Many important decisions with significant implications for the future of our societies are taken under uncertainty, without a full picture of how the different variables the decisions are based on will change over time. For example, the ongoing green transition requires large and urgent societal investments in new energy modes, infrastructure and technology. But the decisions span over a long time-horizon, and there is high uncertainty about future energy prices and demand, and the capacity of renewable resources to replace fossil fuels.
Several classical mathematical tools are used to support decision making under uncertainty, including stochastic optimization and robust optimization. However, with these traditional models it can be difficult to solve optimization problems defined on a large number of scenarios. This means that generally only a small set of scenarios is considered, leading to less well-founded decisions.
In the ERC-funded DECIDE project we will completely rethink the way complex stochastic optimization problems are solved. Instead of solving them based on a fixed set of forecasted scenarios, we will use an iterative process that allows us to generate a palette of near-optimal solutions. Knowing the full spectrum of possible choices enables a much broader discussion of investments, leading to a more transparent and inclusive decision process. The developed models will be tested on data from energy investment models, as well as transport infrastructure problems.
You will join a strong academic team at DTU Management’s Management Science division. Three PhD students and four PostDocs will work on the project, as well as several international experts in operations research.
The project is headed by Professor David Pisinger who has published several papers in the field, and who has supervised more than 30 PhD students.
DECIDE is funded by the European Research Council (ERC-2022-ADG).
Responsibilities and qualifications
As part of the DECIDE project you will be working on developing next generation of tools for decision making under uncertainty. You must:

• Have experience in developing fast algorithms for hard combinatorial optimisation problems.
• Know MIP-models and how to solve them with CPLEX / Gurobi.
• Have knowledge about implementation of metaheuristics.
• Possess some basic knowledge about machine learning and AI would be good, to improve collaboration with other work packages.
• Be passionate for research and for pushing the scientific frontiers.
• Have excellent programming skills.
• Have good collaboration skills.
• Be fluent in English, spoken as well as written.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.
It would be an advantage if you have taken some courses in stochastic optimization or advanced algorithms.
