This paper builds upon a view of economic system and individual economic organization as problem-solving arrangements and presents a simple model of adaptive problem-solving driven by trial-and-error and collective selection. The institutional structure, and in particular its degree of...

Local search algorithms for combinatorial optimization problems are in general of pseudopolynomial running time and polynomial-time algorithms are often not known for finding locally optimal solutions for NP-hard optimization problems. We introduce the concept of epsilon-local optimality and...

This paper assesses the implementation of IMF-supported programs using measures of program interruptions, compliance with conditionality, and the share of committed funds disbursed. The econometric model allows an evaluation of the importance for program implementation of political conditions in...

We present the result of research, developed within Nokia Siemens Networks, to solve the downlink sub-frame allocation problem in Mobile WiMAX (IEEE 802.16) technology in its full complexity, while simultaneously fulfilling real-life constraints on processing power and delay. We describe the...
