Constraint satisfaction problemConstraint satisfaction problems (CSPs) are mathematical questions defined as a set of objects whose state must satisfy a number of constraints or limitations. CSPs represent the entities in a problem as a homogeneous collection of finite constraints over variables, which is solved by constraint satisfaction methods. CSPs are the subject of research in both artificial intelligence and operations research, since the regularity in their formulation provides a common basis to analyze and solve problems of many seemingly unrelated families.
Numerical methods for ordinary differential equationsNumerical methods for ordinary differential equations are methods used to find numerical approximations to the solutions of ordinary differential equations (ODEs). Their use is also known as "numerical integration", although this term can also refer to the computation of integrals. Many differential equations cannot be solved exactly. For practical purposes, however – such as in engineering – a numeric approximation to the solution is often sufficient. The algorithms studied here can be used to compute such an approximation.
Structural adjustmentStructural adjustment programs (SAPs) consist of loans (structural adjustment loans; SALs) provided by the International Monetary Fund (IMF) and the World Bank (WB) to countries that experience economic crises. Their stated purpose is to adjust the country's economic structure, improve international competitiveness, and restore its balance of payments. The IMF and World Bank (two Bretton Woods institutions) require borrowing countries to implement certain policies in order to obtain new loans (or to lower interest rates on existing ones).
Base and superstructureIn Marxist theory, society consists of two parts: the base (or substructure) and superstructure. The base refers to the mode of production which includes the forces and relations of production (e.g. employer–employee work conditions, the technical division of labour, and property relations) into which people enter to produce the necessities and amenities of life. The superstructure refers to society's other relationships and ideas not directly relating to production including its culture, institutions, roles, rituals, religion, media, and state.
Socialist economicsSocialist economics comprises the economic theories, practices and norms of hypothetical and existing socialist economic systems. A socialist economic system is characterized by social ownership and operation of the means of production that may take the form of autonomous cooperatives or direct public ownership wherein production is carried out directly for use rather than for profit. Socialist systems that utilize markets for allocating capital goods and factors of production among economic units are designated market socialism.
History of economic thoughtThe history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day in the 21st century. This field encompasses many disparate schools of economic thought. Ancient Greek writers such as the philosopher Aristotle examined ideas about the art of wealth acquisition, and questioned whether property is best left in private or public hands.
