#2797:

• Fixed adaptive random topology updater
• Adapted default values of the best attraction parameters
• Changed code of the new topology initializer
• Fixed the parameters of the SPSO particle updaters (c parameter is actually (personal|neighbor)bestattraction), reordered the method signature and provided defaults
• Removed the max beyond parameter again
• Updated the sample and updated the unit test
  • In the sample no inertia updating is used, but the topology initializers / updaters of SPSO are used
