Abstract
A fundamental financial problem is budgeting. A firm is given a set of financial instruments \(X=\{x_1,\ldots ,x_n\}\) over a number of time periods T. Every instrument \(x_i\) has a return of \(r_i\) and for time period \(t=1,\ldots ,T\) a price of \(p_{t,i}\). Further for every time period t there is budget \(b_t\). The task is to choose a portfolio \(X'\) from X such that for every time period \(t=1,\ldots ,T\) the prices of the portfolio do not exceed the budget \(b_t\) and the return of the portfolio is maximized. We study the fixed-parameter tractability of the problem. For a lot of small parameter values we obtain efficient solutions for the capital budgeting problem. We also consider the connection to pseudo-polynomial algorithms.
