Final answer:
A program to navigate from one web page to another could use bidirectional search, which operates from both ends towards the middle, but its implementation is complex given web links' nature.
Step-by-step explanation:
Specifically concerning web navigation and search strategies. Writing a program in Python to find a path of links from one web page to another involves implementing a search strategy.
A bidirectional search can be effective in this context as it works from both the starting and target nodes and meets in the middle, which can be faster for large spaces of nodes. However, it is complex to implement bidirectional search on the web due to the nature of web links and the dynamic content of web pages. Using a search engine to implement a predecessor function could be possible by querying for pages that link to a certain URL, but this would depend on the capabilities of the search engine and its index. Moreover, considering the typical structure of hyperlinks as one-way rather than two-way, tracing the path back could be more sophisticated than a straightforward search. A search engine might assist in finding predecessor links, although this relies heavily on the search engine's capabilities and index.
