Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

climate impacts hitting the poorest hardest remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Zero-day flaws are unknown weaknesses in software that attackers can exploit before a fix exists, and current detection methods still miss many of them until after damage is done. Finding these flaws proactively remains one of cybersecurity's hardest problems.

Some believe rewards should go strictly to those who work hardest or perform best, while others argue unequal starting points make pure merit-based systems inherently unfair. This tension remains philosophically unresolved.

While specific puzzle sizes have been fully solved computationally, generalizing the worst-case difficulty formula across all puzzle sizes remains an open combinatorial question. This links recreational mathematics with formal complexity theory.

Wars, droughts, and shipping disruptions can send food prices soaring almost overnight, hitting poorer households hardest. A more resilient global food system could soften these shocks before they cause real hunger.
