A heuristic for the non-unicost set covering problem using local branching
John E Beasley
In this paper we present a heuristic for the non-unicost set covering problem using local branching. Local branching eliminates the need to define a problem specific search neighbo…
A two stage approach for order and rack allocation with order backlog in a mobile rack environment
Cristiano Arbex Valle, John E Beasley
In this paper we investigate a problem associated with operating a robotic mobile fulfilment system (RMFS). This is the problem of allocating orders and mobile storage racks to pic…
A discrete optimisation approach for target path planning whilst evading sensors
J. E. Beasley
In this paper we deal with a practical problem that arises in military mission planning. The problem is to plan a path for one, or more, agents to reach a target without being dete…
A nonlinear optimisation model for constructing minimal drawdown portfolios
C. A. Valle, J. E. Beasley
In this paper we consider the problem of minimising drawdown in a portfolio of financial assets. Here drawdown represents the relative opportunity cost of the single best missed tr…
Quantitative portfolio selection: using density forecasting to find consistent portfolios
N. Meade, J. E. Beasley, C. J. Adcock
In the knowledge that the ex-post performance of Markowitz efficient portfolios is inferior to that implied ex-ante, we make two contributions to the portfolio selection literature…
An algorithm for the optimal solution of variable knockout problems
J. E. Beasley
We consider a class of problems related to variable knockout, where knockout means set a variable to zero. Given an optimisation problem formulated as a zero-one integer program th…
