Many software engineering activities concern optimization problems
characterized by competing goals/constraints and with a bewilderingly
large set of possible choices. So finding good solutions can be hard.
Search-Based Software Engineering (SBSE) is an approach to software
engineering in which search based optimization algorithms are used to
identify optimal or near optimal solutions and to get insight into these
kinds of problems.

In this talk I will provide an overview of SBSE and show how it has been
used to attack optimization problems faced by software engineers. Then
I will present CoGEE (Confidence Guided Effort Estimator), our
recent proposal for software development effort estimation. CoGEE is a
multi-objective evolutionary approach that builds robust estimation models
by simultaneously maximizing the estimation accuracy and minimizing the
uncertainty associated with the estimation model itself. Our proposal
creates a new state-of-the-art that lies within currently claimed
industrial human-expert-based thresholds, thereby demonstrating that our
findings have actionable conclusions for practicing software engineers.
