    dct:description """
              The verification of programs with floating-point numbers computation is an important issue in the development of critical software systems. Computations over floating-point numbers are not accurate, and the results may be very different from the expected results over real numbers. The aim of this thesis is to design a constraint solver over floating-point numbers for program verification purposes. We introduce a new method for solving constraints over floating-point numbers. This method is based on an over-approximation of floating-point constraints using constraints over real numbers. This overapproximation is safe, that’s to say it doesn’t loose any solution over the floats. The generated constraints are then solved with a constraint solver over real numbers. We propose a new filtering algorithm using linear programming techniques, which takes advantage of these over-approximations of floating-point constraints. We introduce also new search methods and heuristics to find floating-point solutions of these constraints. Using our implementation, we show on a set of counter-examples the difference of the execution of programs over the floats with the specification over real numbers.
