Title : Define track

Discussion Sébastien Le Digabel about Speculative search in Nomad:

• Speculative search uses fixed parameters (for each iteration of search) BASEFACTOR = 4.0 (stepLength) and SEARCHMAX = 1 (number of points generated along the direction).
• BASEFACTOR choice explained (opportunistic search in CS + Mesh factor in MADS).
• MADS algorithm iterates on Search and Poll (if search step fails). If search step succeeds, MADS skips Poll and iterates directly on search (especially speculative method which in this case extends to a “line search”) until termination criteria.
• Interesting work on new linesearch-based algorithmic framework in DFO/BBO context
