When the exit criteria are met, the phase causes a gate to be closed to allow the software development life cycle to proceed to the next phase. In one embodiment, the software life cycle includes six phases—a requirements phase, a design phase, a code/unit test phase, a system test phase, a pre-production test phase and a production test phase.

To obtain data pertaining to the surface characteristics of a sample, a control method adjusts a tilted rastered E-beam to in SEM to a first/next tilt condition and navigates the SEM-beam to a sample site. The system performs a fine alignment step. Then the system scans a region of a sample to acquire a waveform. The system analyzes the waveform to determine the DESL value for each edge of interest. The system tests whether there is sufficient information available for each structural edge. If NO, the system repeats the above steps starting by changing the value of the tilt angle to acquire another waveform. If YES, the system determines the height and sidewall angles for each structural edge. Then the system reports the sidewall angle and the structure height for each edge of the structure under test. The system then corrects the critical dimension measurement determined from 0 degrees tilt scanning.

Hence, the invention is a contribution to the field of designing computer implemented systems that test how different trading algorithms work when fed historic data (‘backtesting’). It teaches an efficient and effective data representation that comprises two elements. First, an object-based representation of each trading strategy; each object is instantiated as a ‘strategy instance’. Secondly, a pairing between any tradable instrument and any strategy instance; the pairing is called an ‘account’. A key advantage of the data representation is that the data in each account is held in a matrix format; these are easily and efficiently stored in standard relational databases. Further, operating the method involves large scale matrix operations, which are fast and computationally efficient within a matrix based language. Conventional approaches do not store data in a matrix format and hence fail to achieve the computational efficiency possible with the present invention.
