Pioneer species are those first species that colonize places where previously there were no living beings, like, for example, algae that colonize bare rocks. In general, pioneers species are autotrophs or maintain harmonious ecological interaction with the autotrophic beings (like autotrophic bacteria, lichens, herbaceous plants).
The pioneer community is formed of the species capable to continue to exist under hostile environments. The presence of such species modifies the microenvironment generating alters in abiotic and biotic factors of the ecosystem undergoing formation. Thus, they open way to other species to set up in the place by the creation of the new potential ecological niches.

DFS and BFS Tradeoffs: In general, DFS will have lower memory (space) complexity than BFS since only the information about the states and transitions on the current path needs to be stored. This contrasts with BFS, where all the states and transitions
Depth-First Search: With Depth-First Search (DFS), the model checker begins at the start state and explores each of its outgoing transitions to other states as far as possible along each branch before backtracking and selecting the next transition. DF
