again obtained by Cropper (1985) Modelling was explored, but no substantive conclusions emerged on the geometrical parameters for inclination and magnetic co-latitude; many details of the light-curve and polarization curves remained unexplained, but it was suggested that larger i and smaller are required than had been assumed earlier Simultaneous ve-colour photometry and polarimetry of EF Eri was performed by Piirola, Reiz & Coyne (1987a) with a strong wavelength dependence of the polarization position angle being ound, this being ascribed to Faraday rotation A signi cant change in the circular polarization waveform was noted, indicating a change in geometry since the observations of previous workers A fuller discussion of these data is given in Piirola, Reiz & Coyne (1987b) where the general model was applied The phase dependence of the position angle of the polarization requires eld and accretion geometries more complicated than a simple centred dipole, there being a second emitting region producing a weaker intermediate pulse A value of i D 55 5 is suggested, with the co-latitude, , of the active pole at 38 5 , and the second emitting region at D 145 5 , both nearly at the same longitude, facing the main accretion stream Five-colour polarimetry of RX J02038+2959 was undertaken by Katajainen, Scaltriti, Piirola, et al (2001) with the behaviour of its 4h 6 period favouring a geometry with two pole accretion, and allowing an inclination of i 70 to be assigned Bailey, Axon, Hough, et al (1983) made both photometric and polarimetric observations of the AM Herculis-type binary, E 1405-451, and detected circular polarization at wavelengths beyond 1 m The form of the polarization curve indicted that the accretion column is always in the hemisphere of the white dwarf towards the observer, and that the eld becomes almost parallel to the line of sight at the phase of the minimum For BL Hyi, Piirola, Reiz & Coyne (1987c) found the cyclotron emission peaking in the near infrared (>08 m), with the rotation rate of the position angle of the polarization during the bright phase, and the duration of the circular polarization sign reversal, being consistent with i D 70 10 , and co-latitude of the magnetic pole D 133 10 The basic geoemtry of BL Hyi was also determined by Schwope & Beuermann (1989) A brief description of the polarimetric behaviour of VV Pup was given by Piirola, Reiz & Coyne (1987d), and later by Piirola, Reiz & Coyne (1990), with discussion on the size of the emitting region, and how it appears to change dramatically in size according to wavelength These two stars, together with AM Her, EF Eri and ST LMi, were discussed by Piirola (1988), their behaviour not being adequately explained in terms of the simple model of one narrow emitting region or two diametrically located opposite regions In particular, the behaviour of the position angle of the polarization strongly suggests the existence of more than one discrete emission region, and shows deviations from the simple dipole eld and emission geometry in these systems A more sophisticated approach of modelling, with its application to AM Her, was described by Wickramasinghe, Bailey & Meggitt (1991) Mason, Liebert & Schmidt (1989) made a study of H 0538+608, later to be called BY Cam by Mason, showed the system to have extremely large uctuations from.

Early results of the application of the PSO to type I environments (refer to Section A9) with small spatial severity showed that the PSO has an implicit ability to track changing optima [107, 228, 385] Each particle progressively converges on a point on the line that connects its personal best position with the global best position [863, 870] The trajectory of a particle can be described by a sinusoidal wave with diminishing amplitude around the global best position [651, 652] If there is a small change in the location of an optimum, it is likely that one of these oscillating particles will discover the new, nearby optimum, and will pull the other particles to swarm around the new optimum However, if the spatial severity is large, causing the optimum to be displaced outside the radius of the contracting swarm, the PSO will fail to locate the new optimum due to loss of diversity In such cases mechanisms need to be employed to increase the swarm diversity Consider spatial changes where the value of the optimum remains the same after the change, ie f (x (t)) = f (x (t + 1)), with x (t) = x (t + 1) Since the tness remains the same, the global best position does not change, and remains at the old optimum Similarly, if f (x (t)) > f (x (t+1)), assuming minimization, the global best position will also not change Consequently, the PSO will fail to track such a changing minimum This problem can be solved by re-evaluating the tness of particles at time t + 1 and updating global best and personal best positions However, keep in mind that the same problem as discussed above may still occur if the optimum is displaced outside the radius of the swarm One of the goals of optimization algorithms for dynamic environments is to locate the optimum and then to track it The self-adaptation ability of the PSO to track optima (as discussed above) assumes that the PSO did not converge to an equilibrium state in its rst goal to locate the optimum When the swarm reaches an equilibrium (ie converged to a solution), vi = 0 The particles have no momentum and the contributions from the cognitive and social components are zero The particles will remain in this stable state even if the optimum does change In the case of dynamic environments, it is possible that the swarm reaches an equilibrium if the temporal severity is low (in other words, the time between consecutive changes is large) It is therefore important to read the literature on PSO for dynamic environments with this aspect always kept in mind The next aspects to consider are the in uence of particle memory, velocity clamping and the inertia weight The question to answer is: to what extent do these parameters and characteristics of the PSO limit or promote tracking of changing optima These aspects are addressed next: Each particle has a memory of its best position found thus far, and velocity is adjusted to also move towards this position Similarly, each particle retains information about the global best (or local best) position When the nvironment changes this information becomes stale If, after an environment change, particles are still allowed to make use of this, now stale, information, they are.

Although it is tempting to think of radical change and incremental change as alternatives that we can rationally choose between at any time, this is not the case Often, our decision to use one form of change instead of the other is dictated by forces outside our control These include our position within the rganization, the speed at which change is needed and the level of risk that we can accept Traditional software development methodologies have assumed radical change To this end, the development team delivers software and the users are forced to change overnight As we saw in 6, this limits opportunities for organizational learning and change by our customers This approach has helped foster the image that IT is in exible, dif cult to work with and a barrier to change Agile software development is built on the idea of incremental change quite different from traditional development This reduces risk from development projects and opens opportunities for organizational learning by our users and development teams However, this model still involves risks, most speci cally that change won t happen fast enough or go far enough Agile also extends the incremental improvement model into the development team itself As we have said before, the best Agile teams are themselves learning teams that are constantly improving the way in which they work and adapting to their environment The same dangers hold within the team Having achieved a form of Agility , teams may be tempted to stop changing or to freeze the change in a process document Therefore, we need to change the culture of our development teams just as much as the practices and processes that we follow.
