This work summarizes the theoretical and algorithmic basis of optimized pr- abilistic advising. It developed from a series of targeted research projects s- ported both by the European Commission and Czech grant bodies. The source text has served as a common basis of communication for the research team. When accumulating and re?ning the material we found that the text could also serve as

a grand example of the strength of dynamic Bayesian decision making,

a practical demonstration that computational aspects do matter,

a reference to ready particular solutions in learning and optimization of decision-making strategies,

a source of open and challenging problems for postgraduate students, young as well as experienced researchers,

a departure point for a further systematic development of advanced op- mized advisory systems, for instance, in multiple participant setting. These observations have inspired us to prepare this book.
